1. A 10,000 kg railroad car is rolling at 2.00m/s when a 4000kg load of gravel is suddenly dropped in. What is the car’s speed just after the gravel is loaded?
Relevant Equations
W = 1/2 mv(f)^2 - 1/2 mv(i)^2
3. The Attempt at a Solution [/b]
W = 1/2 (14,000kg)v(f)^2 - 1/2(10,000)(2.0)^2
I'm lost:$
