Question

Two bodies of masses 5grand4kg moving with velocities 10m/s and 12m/s find difference in their momentum

Answer 1

Answer:

two bodies of same mass start from rest and move with velocities of v and 2v respectively find the ratio of their kinetic energies

Answer 2

Hiiiiii dude

m1 = m2 = M v1 = a v2 = - a Using Vcm = m1v1 + m2v2m1 + m2 Vcm = Ma + M( - a)M + M = 0
