Question

A mass m is dropped from rest from a height h above the left hand side of a frictionless bowl where it meets the side of the bowl exactly after falling h and starts to slide down the side of the bowl with some initial velocity where it then collides with a 4m mass sitting at the bottom. The 4m mass makes it exactly up to the rim of the bowl on the right hand side and the m mass makes it up exactly to the rim of the bowl on the left hand side after the collision. R and m are known (a) Find the height h from which m fell initially. (b) Was this an elastic collision? (c) What is the net impulse delivered to just the 4m mass during the collision? What is the net impulse delivered to the combined mass system plus 4m?

Answer 1

Here,

v is the velocity of m before collision

v' is the velocity of m after collision

V is the velocity of 4m after collision
