Question

question 2 (1 point)
when is the average velocity of an object equal to
the instantaneous velocity?
always
never
only when the velocity is constant
only when the velocity is increasing at a
constant rate
question 3 (1 point)
suppose that an object is moving with a constant
velocity. make a statement concerning its
acceleration.
the acceleration must be constantly
increasing.
the acceleration must be constantly
decreasing.
the acceleration must be a constant non - zero
value.
the acceleration must be equal to zero.

Explanation:

For Question 2: Average velocity is total displacement over time, while instantaneous velocity is velocity at a specific moment. When velocity is constant, the velocity at every moment is the same, so average and instantaneous velocity match.
For Question 3: Acceleration is the rate of change of velocity. If velocity is constant, there is no change in velocity, so acceleration is zero.

Answer:

Question 2: only when the velocity is constant
Question 3: The acceleration must be equal to zero.
