A $1500-\mathrm{kg}$ car accelerates from 0 to $25 \mathrm{~m} / \mathrm{s}$ in $7.0 \mathrm{~s}$. What is the average power delivered by the engine $(1 \mathrm{hp}=746 \mathrm{~W}) ?$ a) $60 \mathrm{hp}$ b) $70 \mathrm{hp}$ c) $80 \mathrm{hp}$ d) $90 \mathrm{hp}$ e) $180 \mathrm{hp}$
(a) How long will it take an 850-kg car with a useful power output of 40.0 hp (1 hp equals 746 W) to reach a speed of 15.0 m/s, neglecting friction? (b) How long will this acceleration take if the car also climbs a 3.00-m high hill in the process?
