Expert Solution
Step 1

(3)

acceleration is the rate of change of the velocity of an object with respect to time.

a = ∆v/∆t

Where,

a = acceleration

∆v = change in velocity

∆t = change in time

Then, if the velocity is constant (∆v = 0)

Then,

∆v/∆t = 0

Since, acceleration, a = 0

So, both statements are true
