A 45 kg child slides down a straight frictionless water slide. The slide is 16 m long and set at angle of 28o above horizontal.1.Find the work done by gravity on the child.2.If the child started at rest at the top, what is the speed of the child at the bottom of the slide?
Homework Answers
Concept - find the work done by gravity by
finding the height of the slide. Then use work energy theorem to
find the speed of the child at the bottom of the slide.

A 52.3 kg child slides down a water slide with a velocity of 1.1 m/sec at the top. At the bottom of the slide, she is moving horizontally, y=1.5 meters above the water. She splashes into the water d=2 meters to the left of the bottom of the slide. a: Assuming potential energy to be zero at the water level, what is the mechanical energy of the child at the top of the slide? b: How high is the top...

A child whose weight is 267 N slides down a 6.10 m long slide that makes an angle of 20.0° with the horizontal. The coefficient of kinetic friction between the slide and the child is 0.100. If the child starts at the top with a speed of 0.457 m/s, what is the child's speed at the bottom? (Ignore air resistance)

In a water park, a 40 kg boy slides down a water slide and into a pool of water. The boy starts from rest and hits the water in the pool at a speed of 14 m/s. If the work done on the boy by gravity is 6.5 kJ, how much work is done by friction? a) -4.50 kJ b) -3.62 kJ c) -2.58 kJ d) -5.79 kJ e) -1.38 kJ

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.

Starting from rest at the top, a child slides down the water slide at a swimming pool and enters the water at a final speed of 4.65 m/s. At what final speed would the child enter the water if the water slide were twice as high? Ignore friction and resistance from the air and the water lubricating the slide.
