Question
Consider a stick moving through space that is made up of 4 pieces of mass that have different velocities (the stick is vertically oriented with top piece moving right at 6 m/s, 2nd piece at 5 m/s right, 3rd piece at 4 m/s right, last piece at 3 m/s right).
Each of the the 4 pieces is 2.0kg.
a)Calculate the kinetic energy of the object.
b)What would the answer be if someone used the total mass and average velocity
c)Calculate the kinetic energy of the object for a person moving left at 2.0m/s relative to the rest frame.
Please show work and do all parts for full points :) Thanks!!
Explanation / Answer
Kinetic energy=1/2mv^2
