A 1000 kg race car starts from rest and reaches a speed of 100 km/h in 20 s. What is the power delivered by the car’s engine? (2 points). A 1 kg mass is released from the top of a smooth slide of height 2m. At the bottom of the slide the mass slides on a horizontal surface and stops at a distance of 5 m. What is the coefficient of kinetic friction of the horizontal surface? (3.5 points). The...
