A. 14. If an object moves in the same direction and at a constant speed for 4 hours, which of the following is true?

a. The object's speed changed during the 4 hours.

b. The object's speed and average speed were equal during the entire 4 hours.

c The object accelerated during the 4 hours.

d. The object decelerated during the 4 hours.

B. The object's speed and average speed were equal during the entire 4 hours.  This is correct since the speed and average speed can't change if the object has a constant speed and the constant doesn't change.

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
