Question

A car traveling at a speed of 13 meters per second accelerates uniformly to a speed of 25 meters per second in 5.0 seconds. 11- Calculate the magnitude of the acceleration of the car during this 5.0-second time interval.

Answer 1

`a=2.4\ m/s^2`

Step-by-step explanation:

Given that,

Initial speed of a car, u = 13 m/s

Final speed of a car, v = 25 m/s

Time, t = 5 s

We need to find the acceleration of the car during this 5.0 second time interval. Let a is the acceleration. It can be calculated as :

`a=(v-u)/(t)\\\\a=(25-13)/(5)\\\\=2.4\ m/s^2`

So, the acceleration of the car is
`2.4\ m/s^2`.
