Homework Statement
"You are asked to do an experiment where you will need to use a rotating blade to measure the wind speed. You measure the number of rotations of the blade at 10 different wind speeds, 10 times each and will make a linear fit to determine the wind speed as a function of...
What I did was: Since it was an elastic collision, energy is conserved.
KE Initial = KE Final
KE Initial came out to be, 34 J.
Therefore:
34J = (1/2)(4kg)(v1)^2 + (1/2)(2kg)(v2)^2
Momentum is conserved as well, and therefore Momentum Initial = Momentum Final, which
came out to be 4...
Homework Statement
A 4kg ball moves moving to the east with a speed of 3m/s has an elastic collision with a 2kg ball moving to the west with a speed of 4 m/s.
What is the total momentum of the system after collision?
Determine the velocities of each ball after collision.Homework Equations
