Physics- conservation and dissipation of energy Watch
If the student pushed the trolley up the slope at constant speed, explain why all the work done by the student was not transferred to the gravitational potential energy store of the trolley. [3 marks]

Hi, yes, i figured out that some work done would convert to sound energy due to the wheels squeeling when they spin, to heat energy due to the wheels causing friction.
Hope this helps, Tomas
