A ball is moving towards a wooden box as shown. Its velocity was 1.5 m/s when it was 20 m away from the box and after 5 s, it hit the box. What was the acceleration and final velocity of the ball when it touched the box?
A ball is thrown vertically upwards. when the ball reaches one half of its maximum height, its speed becomes 10m/s (a) How high does the ball rise? (b) Find the velocity and acceleration 1s after it is thrown.
