Question

a cart of mass 50 kg is moving on a straight track with a speed of 12m/s. a mass of 10 kg is gently put into the cart. what will be the velocity of the cart?

Answer 1

hey dear your answer is here..
m1u1+m2u2=(m1+m2)v
50×12+10×0=(50+10)v
600=60v
v=10m/s

so final velocity of both that combination is 10m/s
