Question
Three blocks with mass m1=1 kg, m2=2 kg, and m3=3 kg(no angular momentum or energy) are arranged in order on a frictionless horizontal track which is attached to a vertical circular track at the horizontal track's end. The first mass is struck so that it has speed v1. It collides with m2 elastically. Then m2 slides along and collides with m3 inelastically. The final mass enters the circular track of radius of 1 m and reaches an angle pi/3
a. With what speed does the final mass enter the circular track?
b. With what speed does m2 travel after its collision with m1?
c. What are the speeds of m1 before and after its collision with m2?
d. How much energy is lost during this process?

Expert Solution
Step 1

We are authorized to answer three subparts at a time, since you have not mentioned which part you are looking for, so we are answering the first three subparts, please repost your question separately for the remaining subpart.

Step 2

Given:

The mass m1 = 1 kg.

The mass m2 = 2 kg.

The mass m3 = 3 kg.

Radius of circular track r = 1 m.

Angle gained by (θ) = π/3.
