In the second part of the question it states that this is an elastic collision. Maybe that's why when I use the conservation of energy my number is within .01 of the conservation of momentum answer.
conservation of momentum gives me 1.29
conservation of energy gives me 1.30
Homework Statement
A car moving with an initial speed v collides with a second stationary car that is 52.9 percent as massive. After the collision the first car moves in the same direction as before with a speed that is 31.8 percent of the original speed. Calculate the final speed of the...
Homework Statement
A single constant force F = (2.84i + 4.60j) N acts on a 4.12 kg particle. Calculate the work done by this force if the particle moves from the origin to the point having the vector position r = (1.52i - 2.55j) m.
