check the pic
hint - avg accn = V2-V1/T2-T1
therefore accn=60-18/5-2 =14
hint - avg accn = V2-V1/T2-T1
therefore accn=60-18/5-2 =14

Answer:
The average acceleration between 2 and 5s is 15.33m/s².
Explanation:
The average acceleration is given as,
(1)
Where,
a=average acceleration
v₁=initial velocity
v₂=final velocity
t₁=initial time
t₂=final time
From the question we have,
(2)
Initial time(t₁)=2 second
Final time(t₂)=5 second
For t₁=2 second
By placing t₁=2 second in equation (2) we get;
(3)
For t₂=5 second
By placing t₂=5 second in equation (2) we get;
(4)
By placing all the required values in equation (1) we get;
Hence, the average acceleration between 2 and 5s is 15.33m/s².
