Acrane lifts a 35,00-n steel grinder a distance of 25m in 45s. how much power did the crane require to life the grinder? write your answer in kilowatts.

With the information given, one can presume that:

Work = F • d (so W = 875,000 J)

The equation for power is:

P = W/t (so P = 19444.4 Watts)

1 Watt = 1000 Kilowatts

So the answer would be 19,444,444 kW

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
