Question

If an object of constant mass travels with a constant velocity, which statement is true?

A.momentum is constant
B.acceleration is 0
C.both A & B
D.none of the above

Answer 1

When an object of constant mass travels with constant velocity, its momentum remains constant and its acceleration is zero, because there is no change in velocity over time.

Step-by-step explanation:

If an object of constant mass travels with a constant velocity, momentum is constant because momentum is the product of mass and velocity (momentum = mass × velocity). Since both mass and velocity are constant, the momentum is also constant. Additionally, acceleration is the change in velocity over time (acceleration = change in velocity / time). If the velocity is constant, this means there is no change in velocity, so the acceleration is zero. Therefore, the correct answer is that both momentum is constant and acceleration is 0.
