Homework Answers
By conservation of energy...
PE = KE + Thermal Energy
mgh = .5mv2 + TE
(15)(9.8)(2.8) = (.5)(15)(2.3)2 + TE
Thermal Energy = 372 J

At a playground, a 19-kg child plays on a slide that descends a total of 2.3 meters (vertically). The child starts out at rest at the top of the slide. During the child’s descent, friction does -361 J of work on the child. What speed does the child have at the bottom of the slide?
A 18 kg child slides down a 4.0 m-high playground slide
A 18 kg child slides down a 4.0 m-high playground slide. She starts from rest, and her speed at the bottom is 2.8 m/s. What is the change in the thermal energy of the slide and the seat of her pants?

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 child leaves her book bag on a slide. The bag, which is at the top of the slide, starts from rest and reaches the bottom in 1.73 s. The mass of the book bag is 3, 30 kg, the length of the slide is 3.70 m and the angle of incline is 31.oe. (Assume the +x-axis to be parallel to and down the slide. For all values, enter the magnitude only.) With what acceleration does the bag go down...

a 10 kg child slides down a 4 meter long slide at angle of 30 degrees to the horizontal. at the end of the slide , she is going at a speed of 2.2 m/s. how much energy is converted to internal energy by friction during this slide? (answer in joules) Please explain how to solve this so that I could learn for the future. Thank you!!
