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
