state a reason other than friction, why the power supplied by the motor is greater than the power needed to transport the passengers.

I hope this is gonna be helpful 2 u

Explanation:

The power supplied by the motor is greater than the power needed to transport the passengers.The power produced by an engine is expressed in horse power.When the power developed is measured by the means of a dynamometer or similar breaking device called brake horsepower.. This is the power produced in the combustion chamber of the engine.The torque produced by a motor is bigger than the delivered power because of friction and other mechanical losses.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
