A trolley is moving at constant speed in friction compensated track. Some plasticine is dropped on the trolley and sticks on it. State with a reason what is observed about the motion of the trolley.

A trolley is moving at constant speed in friction compensated track. Some plasticine is dropped on the trolley and sticks on it. State with a reason what is observed about the motion of the trolley.

Since the momentum of the body remains constant (conserved), the trolley slows down (its velocity reduces) since its mass increases

i.e M₁V₁ = M₂V₂ then increase in mass implies/cause a decrease in velocity.
