A 1500 kg car is traveling on a flat surface at 100 km/h. Find the kinetic energy. Assuming no frictional losses so that kinetic energy is transformed to potential energy, if the car then coasts up a hill, how high will it go vertically before it comes to rest?

A 1000-kg car is accelerated from rest to 85 km/h in 10 s. Assuming that no mass is lost and the car accelerates on a flat, horizontal surface, what is the change of the total energy of the car? How much power is required to change this total energy? Would the total energy change and power required change if it were to accelerate in 5 s?

A car of mass 850 kg is initially moving at 110 km/h at the bottom of a large hill. Friction coefficient of 0.9 (rubber on dry asphalt) a) How high up the hill can the car coast (engine disengaged), if work done by friction is negligible? b) If, in actuality, the car is observed to coast up to a height of 22.o m above its starting point, how much thermal energy was generated by friction?

A car of mass M = 1500 kg traveling at 65.0 km/hour enters a banked turn covered with ice. The road is banked at an angle ∘, and there is no friction between the road and the car's tires as shown in (Figure 1). Use g = 9.80 m/s2 throughout this problem. What is the radius r of the turn if θ = 20.0 ∘ (assuming the car continues in uniform circular motion around the turn)?
