An advertisement claims that a certain 1200-kg car can accelerate from rest to a speed of 25 m/s in a time of 8.0 s. What average power must the motor develop to produce this acceleration? Give your answer in both watts and horsepower. Ignore friction losses.A 500-g block is shot up the incline in Fig. 6-6 with an initial speed of 200 cm/s. How far will it go if the coefficient of kinetic friction between it and the incline is 0.150? Use energy considerations to solve the problem.
