20 A car travels at a constant speed of 25 ms¹ up a slope. The wheels driven by the engine exert a forward force of 3000 N. There is a drag force due to air resistance and friction of 2100N. The weight of the car has a component down the slope of 900 N. What is the rate at which thermal energy is dissipated? A zero B 2.3 × 10¹ W C 5.3 x 104 W D 7.5 × 10¹ W C 20 A car travels at a constant speed of 25 ms¹ up a slope. The wheels driven by the engine exert a forward force of 3000 N.
