What Suppose an object in free fall is dropped from a building Its starting velocity is 0 ms Ignoring the effects of air resistance what is the speed in ms of the object after falling 3 seconds?
29.4 m/s
What is the skydiver's downward velocity after 1 second?
Ignoring air resistance, it's about 9.8 m/s.
What is the velocity of a stone dropped of a building 318 meters?
Ignoring any effects due to air resistance, the speed of the stone is zero at the instant it's dropped, and increases steadily to 78.98 meters per second when it hits the ground. The velocity is directed downward throughout the experiment.
If air resistance is negligible then terminal velocity is the velocity of shock waves?
If resistance is negligible, then there is no terminal velocity.
How does air resistance affect terminal velocity?
Without air resistance, there would be no such thing as terminal velocity.

If a ball is thrown vertically up with the velocity of 40m s what would be its velocity after two seconds?
Ignoring air resistance and using g = 9.81 ms-2, velocity = 20.38 ms-1.
If air resistance is negligible then terminal velocity is the velocity of shock waves?
If resistance is negligible, then there is no terminal velocity.
A squirrel drops a nut over a cliff what is the velocity of the nut after 3 seconds?
Ignoring air resistance, the velocity of any object that goes off a cliff is 29.4 meters (96.5 feet) per second downward, after 3 seconds in free-fall.
How does air resistance affect terminal velocity?
Without air resistance, there would be no such thing as terminal velocity.
When a body is projected simultaneously from the top of the building with different initial horizontal velocity which of the two will hit the ground first?
Ignoring air resistance, the horizontal component of velocity has no connection with, and no effect on, the vertical component. Two bodies that leave the top of the building simultaneously with the same vertical velocity hit the ground at the same time, regardless of their horizontal velocities or their masses. That's the same as saying that a bullet fired horizontally from a gun and a bullet or a stone dropped from the gun's muzzle at the same instant hit the ground at the same instant. Strange but true.
How do you find final velocity given height and mass?
the final velocity assuming that the mass is falling and that air resistance can be ignored but it is acceleration not mass that is important (can be gravity) final velocity is = ( (starting velocity)2 x 2 x acceleration x height )0.5
Describe how the velocity and acceleration of an object change as it fell from tall building?
The magnitude of the velocity will increase. The velocity will be downward - and since it increases, the acceleration will be downward. The acceleration doesn't change (it will remain constant at about 9.8 m/sec2), unless air resistance becomes significant.
When an object falls through the air and encounters air resistance its overall speed will be?
Terminal Velocity. This is the velocity at which the accelaration from Earth's gravity and the drag from air resistance reaches equillibrium.
