A piece of dirt falls from the bed of a moving truck. It strikes the ground directly below the end of the truck. (a) What is the direction of its velocity relative to the truck just before it hits? (b) Is this the same as the direction of its velocity relative to ground just before it hits? Explain your answers.
a. The velocity of the dirt is backward relative to the truck just before it hits the ground, (b) The velocity of the dirt is backward relative to the ground just before it hits the ground,
b. The velocity of the dirt is backward relative to the truck just before it hits the ground, (b) The velocity of the dirt is forward relative to the ground just before it hits the ground,
c. The velocity of the dirt is forward relative to the truck just before it hits the ground, (b) The velocity of the dirt is leftward relative to the ground just before it hits the ground,
Ans: b. The velocity of the dirt is backward relative to the truck just before it hits the ground, (b) The velocity of the dirt is forward relative to the ground just before it hits the ground,
