M=200 GRAM=0.2 KG

U=0

V=30 M/S

T=0.1 SEC

F=?

F=MA ,FROM THIS EQUATION WE CAN FIND OUT THE VALUE OF FORCE.

WE HAVE MASS(0.2) KG,TO FIND FORCE FIRST WE HAVE TO FIND OUT ACCELERATION.(BY EQUATION'V=U+AT)

                   >30=O+AX0.1

               >   0.1A=30

                >A=300M/S²

NOW,F=MXA

        F=0.2X300

        F=60 NEWTON

PLAYER'S HAND EXPERIENCES 60 N FORCE.

Given:

  • Mass of ball = 200 gram = 0.2 kg
  • Velocity of ball = 30 m/s
  • Time taken to stop = 1/10 sec

To find:

  • Force experienced by the hand of the player?

Calculation:

Force experienced by the hand of the player will be equal to the change in momentum of the ball with respect to time .

F = \dfrac{\Delta P}{\Delta T}

 \implies F = \dfrac{(mu - mv)}{ T}

 \implies F = \dfrac{ m(u - v)}{ T}

 \implies F = \dfrac{ 0.2(30- 0)}{  \frac{1}{10} }

 \implies F =0.2 \times 30 \times 10

 \implies F =60 \: N

So, force experienced by the hand of the player is 60 N.
