A trolley weighs 200 g. It is pushed along the horizontal ground to a slope. Just before it starts to climb, it has a speed of 18 km / h. As it is driven up the slope,the speed decreases. Frictional forces performing 1.2 J of work act on the trolley during the ascent.
Draw a sketch and describe the energy changes of the trolley during the ascent.
By how much does the kinetic energy of the trolley change during the ascent (from the moment it starts to climb to the moment it reaches its highest position)?
Calculate the change in potential energy of the trolley during the ascent.
How high does the trolley climb?
