a child of mass 25 kg sits at rest at the top of a frictionless slide 2.0m off the ground. He then slides down. what is his kinetic energy at the bottom of the slide?
Homework Answers
v = 2gh =
2x9.8x2.0 =
6.26m/s.
kinetic energy = mv2 / 2 = 25x(6.26)2 / 2 = 489.84J.

A 40-kg child slides down a curved slide starting at the top with an initial speed of 4 m/s. (a) Suppose that the slide is frictionless. Determine the speed of the child when she is 3 m below her starting height. (b) Suppose that the slide has friction. Determine the speed of the child when she is 5 m below her starting height if she starts from rest and 300 J of thermal energy is dissipated during the motion.
