A car exserting a force of 2250 Newton accelerates uniformly so that it acquires a velocity of 72 km per hour find the horsepower required to maintain its velocity
Asked by Samrat | 30 Jun, 2018, 09:57: AM
answered-by-expert Expert Answer
power = force × velocity
 
velocity = 72 km/hr = 72×(5/18) = 20 m/s
 
power = 2250×20 = 4500 W = 4500 / 746 = 6.03 hp
