Question

a body mass 5kg moving with a velocity of 30m/s collide with another body mass m in the same direction with a velocity of 20m/s . if both bodies now move in the same direction with a velocity of 10m/s. calculate the value of m​

Answer 1

Answer:

A body P of mass 5kg moving with a velocity of 30 m/s collides with another body q moving in the opposite direction with a velocity of 20 m/s. If the bodies now move in the direction of P at velocity 10m/s.Calculate the mass of q.

Answer 2

Answer:

Assuming inelastic

m1v1 + m2v2 = (m1+m2)vf

5(30) + m2(-20) = (30+m2)10

Solve for m2
