A car's velocity changes from 0 m/s to 40 m/s in 5 seconds. What is the average acceleration of the car? (Show work)
Answer:
Acceleration, \(a=8\ m/s^2\)
Explanation:
Given that,
Initial velocity of the car, u = 0
Final velocity of the car, v = 40 m/s
Time taken, t = 5 s
Let a is the acceleration of the car. It can be calculated using first equation of motion as :
v = u + at
v = at
40 = a × 5
\(a=8\ m/s^2\)
So, the acceleration of the car is \(8\ m/s^2\). Hence, this is the required solution.
