Question

You toss a small ball vertically up in the air. How are the velocity and acceleration vectors of the ball oriented with respect to one another during the ball’s flight up and down?

Open in App

Solution

When go upward velocity decreases and at maximume height zero velocity. Accelartion is -g(accelaration due to gravity, negative)
when the ball reach max.Height it fall down with velocity.Accelaration is g.
