Problem 1 The downhill racer team is testing a new design. There are 4 wheels each with a diameter of 0.4 m and a mass of 2.0 kg. The rest of the cart has a mass of 20 kg. A spring-loaded brake applies a constant force of 50 N on the two rear wheels. The coefficient of friction between a brake pad and a wheel is 0.7. The cart is traveling down a slope of 0 = 10° at 13.5 km/hr when the brake is applied. Determine how far the racer will travel down the slope until it stops. Model the wheels as uniform thin discs.
