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.

A 6.00 Kg mass initially at rest slides down a ramp which makes
an angle of with horizontal at a
height of 5.0 m above the bottom of the slide and hits a 10.00 Kg
mass which is at rest, after collision, the 6.00 Kg mass bounces
back with a velocity of 0.60 m/s and 10.0 kg mass slides forward on
level. If the coefficient of kinetic friction for the incline is
