Answer 2

Question:

A bowler bowled at a speed of 40 m/s. An indian cricketer hits the ball, its moves in opposite direction with a speed of 60 m/s. What is the acceleration of the ball if time taken is 10 seconds ?

Solution:

To find the acceleration of the ball if time taken is 10 seconds = ?

We know that,

$\bf Acceleration, a = \dfrac{v-u}{t}$

$: \implies \sf \dfrac{60-40}{2}$

$: \implies \sf \dfrac{20}{2}$

$: \implies \sf 10 \: m/s^2$

$\therefore$ The acceleration of the ball if time taken is 10 seconds is 10 m/s².
