When the ball is at its peak, what is v y? The green vector shown is the velocity vector of the ball, v y. Consider the motion of the ball only while it is in the air and not in your hand (If it's in your hand, it's not considered free fall.). Restart.Īnimation 2 shows the ball thrown upward such that it travels upward, reaches some maximum height, and falls back to your hand at the same height at which is was first thrown. If the +y direction is defined to be downward, then the acceleration is +9.8 m/s 2. If the +y direction is defined to be upward, then the ball's acceleration is constant and has a value of -9.8 m/s 2. Its motion is described as free fall (position is given in meters and time is given in seconds). Please wait for the animation to completely load.Ī ball is dropped from rest near the surface of Earth as shown in Animation 1. 2.19: A tennis ball launcher shoots a tennis ball into the air.
