A car starting from rest is uniformly accelerated so that its velocity in 5seconds is 36ms-1. Find its acceleration
To find the acceleration of the car, you can use the formula:
acceleration = (final velocity - initial velocity) / time
Given:
Initial velocity (u) = 0 m/s (starting from rest)
Final velocity (v) = 36 m/s
Time (t) = 5 seconds
Plug the values into the formula:
acceleration = (36 m/s - 0 m/s) / 5 s
Simplifying the equation gives:
acceleration = 36 m/s / 5 s
Dividing the numerator by the denominator:
acceleration = 7.2 m/s²
Therefore, the acceleration of the car is 7.2 m/s².
