an elevator is moving upward at constant speed. if you weigh 700 n on the scale when the elevator is at rest, then the scale now reads?

Awheel rotates without friction about a stationary horizontal axis at the center of the wheel. a constant tangential force equal to 82.0 n is applied to the rim of the wheel. the wheel has radius 0.150 m . starting from rest, the wheel has an angular speed of 12.8 rev/s after 3.88 s. what is the moment of inertia of the wheel?

Work = force × a. work b. energy c. distance d. momentum

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =
