Choose the false statement regarding work done by a force on an object.   The amount of work doesn't depend on the direction of the force relative to the motion.     The amount of work will be greater if the change in position due to the force is greater (for the same magnitude of force).     The amount of work will be greater if the amount of force is greater (for the same change in position due to the force).     The amount of work done by a force will equal the change in kinetic energy of the object, if the force is the only force.

Two people push identical crates, so that they slide along a 10 m stretch slippery floor. Each pushes with the same magnitude of force, but person B applies their force at an angle as shown V There is no friction between the crates and the floor. Which person does less work? O A A B both do the same work, and it is more than zero both do zero work B

There are three different ways to get from location A to location E in the diagram below. In path 1, you take an elevator directly from location A straight up to location E. In path 2, you walk from A to B, climb a rope from B to C, then walk from C to E. In path 3, you walk from location A to D, then climb a ramp up to location E. The following questions focus on the work done on a 51 kg person by the Earth while following each of these paths. B = E A Taking the origin at location A, the coordinates of the other locations are: 7 B = (-3, 0, 0); 7c = ( -3, 12, 0 ) ; p = ( 39, 0, 0); > = { 0, 12, 0). (a) Path 1 (A to E): What is the displacement vector Ar for the path from A to E on the elevator? AT = (0,12,0) = D m (b) What is the gravitational force acting on the person along path 1, as a vector? (-0, -3.2e3,0) N X (c) What is the work done by the gravitational force of the Earth on the 51 kg person during the elevator ride from A to E? W1 F.Ar (d) Path 2 (A to B to C to E): What is…
