A player throws a ball upwards with an initial speed of 29.4 m s-1.

To what height does the ball rise and after how long does the ball return to theÂ playerâ€™s hands ?
(Take g = 9.8 m s-2and neglect air resistance).

Initial velocity of the ball,Â uÂ = 29.4 m/sÂ

At maximum height, the velocity of the ball becomes zero.

Final velocity of the ball,Â vÂ = 0Â

Acceleration,Â aÂ = â€“ g = â€“ 9.8 m/s2 Â

Using third equation of motion,Â

Height to which the ball rises is given by,Â

What is the most essential thing to study the motion of a body?

The most essential thing to study the motion is reference frame. Rest and motion are relative terms. It means that an object in one situation can be in rest but in another situation, the same object will be in motion.
