When Rae dropped a bowling ball from a height of 8 meters At which distance above the ground was the ball most likely moving at the greatest speed?
Still accelerating til it hits earth. ====================================== The height from which she dropped the ball is irrelevant. In any case, the ball was most likely moving at the greatest speed just as it hit the ground. The answer to the question is: zero.
At what point does the ball have an instantaneous velocity of zero?
The ball has an instantaneous velocity of zero at the highest point of its trajectory. This is because at that point, the ball changes direction from going up to coming down, causing its velocity to momentarily be zero before increasing in the opposite direction.
A ball is thrown horizontally from a window on the second floor of a building What is the vertical component of its initial velocity?
The vertical component of the initial velocity of the ball thrown horizontally from a window is zero. The ball's initial velocity in the vertical direction is influenced only by the force of gravity, not the horizontal throw.
Why does a ball you toss into the air not fall right away to the floor?
The ball is thrown with an initial velocity, and gravity slows it down as it rises. At its peak, the ball's velocity is zero before it begins to fall back to the ground. This is due to the balance between the initial force and gravity acting on the ball.
What is its velocity at the highest point of a ball vertically upwards?
At the highest point of a ball's vertical motion, its velocity is zero. This is because the ball briefly comes to a stop before falling back down due to gravity.
If a small marble is dropped straight downward what is the initial velocity of the marble?
The initial velocity is zero. In most basic physics problems like this one the initial velocity will be zero as a rule of thumb: the initial velocity is always zero, unless otherwise stated, or this is what you are solving for Cases where the initial velocity is not zero examples a cannon ball is shot out of a cannon at 50 mph a ball is thrown from at a speed of 15 mph etc
Can a body have zero velocity and still can be acclerating?
Yes. You are holding your hand out. A tennis ball is floating just above it. The velocity of your body relative to the ball is zero. Why is the ball floating? Because you and the ball and the whole elevator are accelerating down to the ground. ---- Here's a proof by reductio ad absurdum that it's possible: If it were not possible for a body to have zero velocity and be accelerating, once anything stopped moving it could never move again.

A boy catches a ball while standing on roller skates What happens to the boy's velocity and the ball's velocity?
The ball's velocity changes to 0m/s and the boy's stays the same.
Velocity time graph for a body dropped from a certain height?
The velocity-time graph for a body dropped from a certain height would show an initial spike in velocity as the object accelerates due to gravity, reaching a maximum velocity when air resistance equals the force of gravity. After this, the velocity would remain constant, representing free fall with a terminal velocity. When the object hits the ground, the velocity suddenly drops to zero.
Can an object have zero velocity but still have an acceleration?
A simple example is a ball tossed into the air. When the ball reaches its apex -- its highest point -- its instantaneous velocity is zero. If we assume that up is the positive direction, the ball's velocity is positive when it is initially tossed into the air, but it slows immediately. That is, its velocity becomes less positive until it reaches zero velocity. After that point, the velocity becomes increasingly negative (because down is the negative direction). Until the ball returns to earth and reaches the height at which it was initially thrown, its average velocity is non-zero. If the ball is allowed to hit the ground, its average velocity will be slightly negative, which is still non-zero. But it still had an instant -- at its apex -- when its velocity was zero.
What is the momentum at the highest point of a ball thrown vertically upwards?
The highest point is the point where the ball's velocity transitions from upward to downward. At that instant, the ball's speed, velocity, momentum, and kinetic energy are all exactly zero.
What is the acceleration of the ball during any of these time intervals and at the moment the ball has zero velocity?
The acceleration of the ball is constant during any time interval where the velocity changes. At the moment the ball has zero velocity, the acceleration is the same as it was during the time interval when the velocity was changing. This can be calculated using the formula acceleration = change in velocity / change in time.
