उत्तर

Given:
Initial speed of the ball, u = 50 m/s
Acceleration, a = −10 m/s2
At the highest point, velocity of the ball is 0. 

\[s = \frac{v^2 - u^2}{2a}\]
   ⇒\[s = \frac{\left( 0^2 - {50}^2 \right)}{2 \times \left( - 10 \right)} = 125 \text{ m } \]

Maximum height = 125 m

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

  1. What is the direction of acceleration during the upward motion of the ball?
  2. What are the velocity and acceleration of the ball at the highest point of its motion?
  3. Choose the x = 0 m and t = 0 s to be the location and time of the ball at its highest point, vertically downward direction to be the positive direction of x-axis, and give the signs of position, velocity and acceleration of the ball during its upward and downward motion.
  4. To what height does the ball rise and after how long does the ball return to the player’s hands? (Take g = 9.8 m s–2 and neglect air resistance).

Calculate the velocity with which the balls were thrown and the exact time interval between their throw.
