Answer 2

Given:-

A cricket ball of mass 0.20 kg is moving with a velocity of 1.2 m/s.

He $is$able to stop the ball in 0.10 s

To find:

Find the average force applied by the player.

Solution:

In order to find the force we need to know acceleration first,

So, as we know

Acceleration = (v – u)/t

where,

⇒ Initial velocity = " u "= 1.2 m/s

⇒ Final velocity = " v " = 0

⇒ Time = " t " = 0.10 s

Now, let's substitute the values

= (0 – 1.2)/0.10

= –12 m/s²

Now we got acceleration

So,

⇒ F = m × a

Here,

Force = " f "

mass = " m "

acceleration = " a "

Now,

⇒ F = 0.2 × –12

⇒ F = ( –2.4 N)

Therefore,

The average force applied by the player is (–2.4 N)
