13. A crane uses an electromagnet to lift a vehicle at a junkyard. The combined mass of the vehicle and electromagnet is electromagnet is 4360 kg. If the motor on the crane lifts the vehicle and electromagnet up 8.85 meters at a constant rate of 4.0 m/s, what is the power output of the crane's motor? (Neglect friction) ​

Two vectors are shown. which statement best compares the vectors? vector x has greater magnitude than vector y. vector y has greater magnitude than vector x. the vectors have the same displacement. the vectors have the same direction.

True or false graphs must include scales that increase by the same amount

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
