Please solve it is urgent plzz plzzz
Dear Student,
Given,
Mass of the boy, m1 = 50 kg
Speed of the boy, v1 = 5 m/s
Mass of the trolley, m2 = 20 kg
Speed of the trolley, v2 = 1.5 m/s
Let their common velocity be V
Momentum of the system (boy + trolley) before the boy jumps,
Momentum of the system after the boy jumps on the trolley
From conservation of momentum, we get
Thus the common velocity is 4ms-1.
Regards
