A 2,050 kg roller coaster cart is pulled by a tow cable at a constant speed of 1.9 m/s to the top of a 53.5 m tall ramp that has a 40° incline. The coefficient of friction between the cart and the roller coaster ramp is μ = 0.10. When the roller coaster cart makes it to the top of the ramp, the cable breaks and the cart accelerates down to the bottom of the ramp. tow cable, You might need: Calculator Calculate the work done by friction on the roller coaster cart as it rolled back down the ramp after the cable broke. kJ 53.5 m Write your answer to three significant figures.
