Question

Martin is given work to solve. Indicate if each is TRUE or FALSE.(Give a brief explanation for each) The work done by the gravitational force does not depend on the path that an object takes in going from its initial height to its final height. A Cadillac and an F-150 collide with one another, lock bumpers, and slide together after the crash. This is an example of an elastic collision. A boy and a girl sitting on a merry-go-round at different distances from the axis of rotation move with different angular velocities. In the absence of air resistance the motion of center of mass of a firecracker will change after it explodes. The gravitational force exerted by the Sun on Earth does no work if we

Explanation / Answer

A) True (because Gravitational force is a sonservative force)

B) False (It is an examle of completely inelastic collision)

C) False (All particles have same angular speed)

D) False

E) Question does not present

F) True (Force is always perpendicular to displacement)

G) True

H) False

I) True
