Question

A ball of mass 0.1 kg hits the hands of a player with a velocity of 20 metre per second power -1 and it and is brought to rest in 0.01 second find the regarding force applied by the hand of the player?


plz plz plz plz plz plz urgent ​

Answer 1

Answer:

200N

since it is known that the ball initial velocity was 200 metre per second and it was stop by the player so its final velocity became zero metre per second and the time interval in which this whole incident occur was. 0 .01 second so we can find the acceleration with which the player stop the ball and you can see in the solution acceleration is given negative because it is opposite to the direction of of velocity initial velocity which gives acceleration as 2000 metre per second square and now to find the force applied by the player formula force equal to mass into to acceleration is applied and which gives the answer as 200
