WebThe formula for the m.o.i. of a pulley is 1/2mr^2, where m is the mass and r is the radius. So the m.o.i. of your pulley would be I=1/2*5kg*.25m^2=.156kg*m^2. The product of the m.o.i. and the angular velocity is going to equal the torque (rotational force) on the pulley. The tension in the rope, in turn, is equal to the torque on the pulley ...

How do physics solve elevator problems? [Ultimate Guide!]

WebFor a mass m= kg, the elevator must support its weight = mg = Newtons to hold it up at rest. If the acceleration is a= m/s² then a net force= Newtons is required to accelerate the … WebWhat is the average power the elevator exerts during this trip? The work done by the elevator over the 100 meters is easily calculable: W = mgh = (1000) (9.8) (100) = 9.8×105 Joules. The total time of the trip can be calculated from the velocity of the elevator: t = = = 25 s. Thus the average power is given by: P = = = 3.9×104 Watts, or 39 kW.
