Originally Answered: A boy of mass 50 kg running at 5 m per second jump onto a 20 kg trolley traveling in the same direction at 1.5 m per second full stop. What is their common velocity?
Momentum Problem
Given:
m1 = 50 kg
v1 = 5 m/s [E]
m2 = 20 kg
v2 = 1.5 m/s [E]
v3 = final velocity
Foemula:
m1v1 + m2v2 = (m1 + m2) x v3
We need to find v3
v3 = (m1v1 + m2v2) / (m1 + m2)
= (50x5 + 20x1.5) / (50 + 20)
= 280 / 70
= 4 m/s [E]
The final velocity is 4 m/s [E].
