Question

If a body of mass m with a velocity of v hits a wall and rebound with same velociry what is change in momentum

Answer 1

Answer:The answer is 0

Explanation:lets us the conservation of momentum formula

Here,

M1=M2=m

V1=V2=v

U=0

m1u1+m2u2=m1v1+m2v2

m(u) =v1(m1-m2)

But

U=0 and mass pf both objects is same

0=0

Change in momentum =0
