Answer:
Acceleration is 3m/s2
Explanation:
From the question, the formula for acceleration is ∆velocit÷∆time.
V1=9m/s
V2=18m/s
T1=0 seconds
T2=3 seconds.
V1 represent initial velocity
V2 represent final velocity
T1 represent initial time
T2 represent final time.
Acceleration=v2-v1÷T2-T1
=18-9/3-0
=9÷3
=3m/s2.
Acceleration is 3m/s2.
Acceleration is the rate of change of velocity of a body per unit time.
