he simplified diagram below shows a slide PQ at a playground. The slide is 3 m long 
and 1,5 m high. A boy of mass 40 kg and a girl of mass 22 kg stand at the top of the 
slide at P. 
 
The girl accelerates uniformly from rest down the slide. She experiences a constant 
frictional force of 1,9 N. 
 
The boy falls vertically down from the top of the slide through the height PR of 1,5 m. 
Ignore the effects of air friction.
