Explanation:
ACCELERATION IS THE RATE OF CHANGE OF VELOCITY
i.e a = ΔV/ Δt where ΔV is final velocity – initial velocity and Δt is t final – t initial
a = (45–15)/5= 6 km/s²
The average acceleration of the car during these 5 seconds = a = 6 km/s^2
What is average acceleration ?
Average acceleration refers to the rate of change of velocity for that interval per time
given
v(initial) = 15 km/s
v( final ) = 45 km/s
time interval = 5 seconds
a (average acceleration) = (v( final ) - v(initial)) / time interval
a = (45 - 15) / 5
a = 6 km/s^2
average acceleration of the car during these 5 seconds = a = 6 km/s^2
