Question

A man catches a ball coming with speed of 72 km/hr in two seconds if mass of ball is 200g Find the force exerted on his hands

Answer 1

Answer:

75%

Explanation:

ball is coming with a speed of 72 km in 2 secs so he can catch the ball

Answer 2

Answer:

force exerted by the ball will be in the following way

Explanation:

given data :-

v=72km/hr=20m/s

m=200g=0.200kg

t=2s

to find value of force:-

f=mv/t

f=20xo.200/2

f=4/2

f=2

therefore force = 2N
