Question

a body of mass 2kg moving with auniform velocity 40m/s collides with another at rest .the 2 together begin to movevwithin a velocity 25m/s .find the mass of the other

Answer 1

m1×v1=m2×v2
2×40=m2×25
80/25=m2
3.2=m2
mass of the second obnect is 3.2 kg..

hope it helps

Answer 2

A body of mass 2kg moving with uniform velocity of 40 m/s collides with another body at rest. If the two ... body at rest. If the two bodies move together with a velocity of 25m/s, mass of the other body is.
