On a roller coaster ride the total mass of the cart - with passengers included - is 305 kg. Peak K is at 47.0 m above the ground, peak L is at 21.5 m. The speed of the cart at K is 15.1 m/s, at L it is 12.7 m/s. (The wheel mechanism on roller coaster carts always keeps the carts safely on the rail.) How much energy is lost due to friction between the two peaks?
