Question

<< Consider the stationary situation shown in the sketch.
The effect of friction is negligible. The 3 kg mass is joined
to the 4 kg trolley by a string passing over the pulley.
When the 3 kg mass piece is released, it falls and
accelerates the trolley 2 m to the top of the runway. In
the process, the trolley rises 1 m. Calculate:
in the gain in potential energy of the trolley on reaching
the top of the runway and
in the speed of the trolley at the top of the runway.
Take g = 10 ms?
2 m
4 kg
3 kg
30°
