when child slides down,
(a) & (b) gravitational potential energy decrease and this decrease in potential energy results into Increase in kinetic energy.
(c)
since nothing is mention about spring in question. hence, No change in elaatic potential energy of system.
(d)
if fricrion is present on the surface,
friction results into heat dissipation, which results in loss of internal energy of system.

A 29.00-kg child initially at rest slides down a playground slide from a height of 3.10 m above the bottom of the slide. If her speed at the bottom is 2.40 m/s, how much energy is lost due to friction?
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?
9 The ball is allowed once more to slide down the slide-slot, starting at rest from point R. However, this time the slide-slot is unconstrained horizontally so that it is free to slide on the table. While sliding, the ball is always in contact with the slide-slot. The mass of the slide-slot is 500 g. gravitational acceleration (g) of a free-falling object is 10 m s-2. As the ball slides down the curved surface, from point R to point T,...
A 27 kg child slides down a playground slide at a constant speed. The slide has a height of 3.8 m and is 7.4 m long. Using the law of conservation of energy, find the magnitude of the kinetic friction force acting on the child.
a block with a mass of 2.5 kg starts from rest at the top of the
apparatus shown below. it then slides without friction down the
incline, and collides with a spring attached to a wall. The spring
has a spring constant of K=120N/m. Using the principle of energy
conservation,
a. find the initial gravitational potential energy of the block
at point A
b. find the kinetic energy of the block at point B
c. what is the velocity of...
A 33 kg child slides down a playground slide at a constant speed. The slide has a height of 4.0 m and is 8.0 m long. Part A Using the law of conservation of energy, find the magnitude of the kinetic friction force acting on the child.
Conservation of energy A child on a sled slides from rest from the top of a 20.0 m high very slippery hill. The total mass of the child and the sled is 30.0 kg. Treat the bottom of the hill as a reference. a. b. c. d. e. What is the kinetic energy of the child and sled at the top? What is the potential energy at the top? What is the potential energy at the bottom? What is the...
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.

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 4.48 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. I tried doing what the previous answers had but I couldnt come up with the correct answer.
