a) The speed of the man at the bottom of the slide is 8.45 m/s.
b) The man's kinetic energy is 545.3 J.
c) The man will travel a distance of 37.3 m before coming to rest.
A 76 kg man starts from rest at the top of a 12.0-m long water slide that is inclined 65° with the horizontal. In sliding down, he encountered a frictional force of 45.0 N.
(a) What is the speed of the man at the bottom of the slide?
(b) What is his kinetic energy?
(c) Suppose the man landed horizontally into the water, how far will he travel before coming to rest? Assume that the frictional force is the same underwater.
