8. A 28.00-kg child initially at rest slides down a playground slide from a height of 3.30 m above the bottom of the slide. If her speed at the bottom is 2.20 m/s, how much energy is lost due to friction? J

Step 1
00 kg Height from the ground (h) = 3.30 m Acceleration due to gravity (g) = 9.8 m/s^2 Potential energy (U) = mgh Potential energy (U) = 28.00 kg * 9.8 m/s^2 * 3.30 m Potential energy (U) = 905.52 J Show more…

A 25 kg child slides down a 4.0 m high playground slide. She starts from rest, and her speed at the bottom is 1.0 m/s. What is the thermal energy that was released in this process? Hint: Consider the initial and final energies.

A child whose weight is 297 N slides down a 6.60 m playground slide that makes an angle of 38.0° with the horizontal. The coefficient of kinetic friction between the slide and child is 0.160. (a) How much energy is transferred to thermal energy? (b) If she starts at the top with a speed of 0.335 m/s, what is her speed at the bottom?

A child whose weight is $267 \mathrm{~N}$ slides down a $6.5 \mathrm{~m}$ playground slide that makes an angle of $20^{\circ}$ with the horizontal. The coefficient of kinetic friction between slide and child is $0.10$. (a) How much energy is transferred to thermal energy? (b) If she starts at the top with a speed of $0.457 \mathrm{~m} / \mathrm{s}$, what is her speed at the bottom?
