Question

A railway wagon of mass 0.5 tonnes and moving with a velocity of 10 kmh–1 is hit from behind by another railway

wagon of mass 1.5 tonnes and moving with 15 kmh–1, such that after collision they move together. Calculate the

final velocity of the wagons.​

Answer 1

Answer:

Explanation: final velocity= mv +MV / M+ m

=.5*10 + 1.5*15 /.5+1.5 =5+7.5 /.2 = 12.5/.2 =62.5
