Question

two object of same masses hit persons namely and b with speed of 20km/hr and 50km/hrrespectively and comes to rest instantaneously which object will exert more force on that person? justify

Answer 1

Two object of same masses hit persons then the body b moving with 50 km/h will exert more force as f=mv so as the velocity increases then the force will also increase

Answer 2

F= ma
So, if m1 = m2
Force is olely dependent on velocity

So, more the velocity of the body, more is the force applied

So, Object of speed 50 km/h will exert more force
