A ball of mass m rolls off a cliff of height h with a horizontal velocity v it reaches the ground with vertical speed of?
If one assumes air resistance to be negligible, then:
final velocity = sqrt( g * 2 * h )
where g is 9.8 metres per second per second.
The quantities v and m do not matter, because gravitational acceleration does not depend on mass (all objects fall at the same rate) and because the horizontal velocity is independent of the vertical velocity.

William tell shoots an apple off a tree 20.0 meters away and 4.0 meters high The arrow is released from 1.0 meter above ground The arrow travels for 0.500 seconds. What's the velocity of the arrow?
Interesting! Horizontal distance covered by arrow=20m=Vx(t),put Time=t=0.5s, so Vx=20/.5=40m/s.Now let us consider vertical motion of the arrow,Vertical distance=4m-1m=3m. so Use Second equation of motion now.Y=Vy(t) - gt2/2.Subtituting the values,3=Vy(0.5) - 9.8(.5)2/2. Solving for Vy, we get,Vy= 8.45m/s and Vx=40m/s. nowV2=(Vx2+Vy2) or V2=(8.45)(8.45)+(40)(40)=71.40+1600=1671.40m/s, soV=(1671.40)1/2=40.88m/s. That is the answer!
Are ladder rungs horizontal or parallel?
Ladder rungs are typically horizontal, meaning they are perpendicular to the vertical side rails of the ladder. Each rung is parallel to the ground when the ladder is in use.
How do you calculate the horizontal distance traveled by an object if you are given the horizontal velocity and time in the air?
You cannot because you do not know how long before the object falls to the ground and so stops moving.
A projectile fired from the ground follows a parabolic path The speed of the projectile is minimum at the top of its path?
At the top of its path, the vertical component of the projectile's velocity is zero, making the overall speed minimum. This occurs because gravity slows down the projectile's upward motion until it stops momentarily before falling back down. The horizontal component of the velocity remains constant throughout the motion.
Why horizontal dropping is faster than oblique?
The very question is not precise. What is meant by faster? Whether we drop horizontally or obliquely the vertical component of the velocity alone changes with time and that too controlled by the acceleration due to gravity. The horizontal component would remain the same through out the flight. If you mean the time of falling on the ground, of course horizontal projection will be sooner than the oblique one. This is because the body has to go up and come down. Hence the time of flight will be double that in case horizontal projection.
If a rock is dropped and a ball is thrown horizontally at the same initial elevation Which will have the greater speed when it reaches ground level?
The thrown ball will have a greater speed when it reaches ground level because it has a horizontal component of velocity in addition to the vertical component. The rock only has a vertical component of velocity due to gravity.
When you jump upward your hang time is the time your feet are off the ground Does hang time depend on your vertical component of velocity when you jump your horizontal component of velocity or both?
Hang time depends on your vertical component of velocity when you jump. The higher the vertical velocity, the longer your feet will be off the ground. The horizontal component of velocity does not affect hang time.
A projectile is fired horizontally from a gun that is 71.0 m above flat ground emerging from the gun with a speed of 250 ms What is the magnitude of the vertical component of its velocity as it st?
If it's fired horizontally, then its initial vertical velocity is zero. After that, the vertical velocityincreases by 9.8 meters per second every second, directed downward, and the projectile hitsthe ground after roughly 3.8 seconds.Exactly the same vertical motion as if it were dropped from the gun muzzle, with no horizontal velocity.
Will a ball drop rest reach the ground quicker than the one lunched from the same height but with and initial horizontal velocity?
No. What counts in this case is the vertical component of the velocity, and the initial vertical velocity is zero, one way or another.
A rock is dropped at the same instant that a ball in the same elevation is thrown horizontally which will have the greater speed when it reaches ground level?
The rock will have a greater speed when it reaches the ground level compared to the ball thrown horizontally because the rock will be accelerated by gravity as it falls vertically, while the ball thrown horizontally will only have its initial horizontal velocity.
How does the angle of release affect the motion of a projectile both vertical and horizontal?
Smaller angles will result in a larger horizontal velocity and smaller vertical velocity. The times of flight will also be shorter since it's closer to the ground. Larger angles have a larger vertical velocity and smaller horizontal velocity. Time of flight will be much longer since it is higher above the ground. As for distance, 45 degrees will result in the greatest distance and for every distance before the furthest one there is an angle above 45 degrees and an angle below 45 degrees that will result in that distance.
What happens when you increase the horizontal velocity to the maximum in a projectile motion?
Increasing the horizontal velocity to the maximum in a projectile motion will cause the object to travel further horizontally before hitting the ground. This is because the horizontal velocity determines how far the object will travel in the horizontal direction before gravity pulls it down. The vertical motion of the object will remain the same, but the increased horizontal velocity will result in a longer horizontal distance traveled.

A rock is thrown upward at an angle of 50 degree with respect to the horizontal As it risesm its horizontal component of velocity?
If you ignore the effect of the air grabbing at it and only figure in gravity, then the horizontal component of velocity is constant, from the time the stone leaves your hand until the time it hits the ground. Makes no difference whether you toss it up, down, horizontal, or on a slant. Also makes no difference whether it's a cannonball, a stone, or a bullet.
When projectile has maximum horizontal range?
A projectile has maximum horizontal range when it is launched at an angle of 45 degrees to the horizontal. This angle allows for the ideal balance between the horizontal and vertical components of the projectile's velocity, ensuring that it travels the farthest distance before hitting the ground.
Will the velocity of an object increase decrease or remain constant as it reaches the ground?
The velocity of an object will increase as it falls towards the ground due to the acceleration of gravity. However, once it reaches terminal velocity, its velocity will remain constant.
What would happen if the initial horizontal velocity was increased?
Increasing the initial horizontal velocity of an object would cause it to cover more horizontal distance in the same amount of time, leading to a longer horizontal range. The object would maintain the same vertical acceleration due to gravity, so it would still follow a parabolic trajectory but reach a farther horizontal distance before hitting the ground.
