Question

a car travelling at 36km / h accelerates uniformly acceleration final 2m / s ^2 find its velocity in 5 second ​

Answer 1

v = 20 m/s

Step-by-step explanation:

Given that,

Initial speed of the car, u = 36 km/h = 10 m/s

Acceleration of the car, a = 2 m/s²

We need to find the final speed of the car in 5 seconds. Let the final speed is v. So,

v = u +at

Substitute all the values,

v = 10+2(5)

= 10+10

= 20 m/s

So, the final speed of the car is 20 m/s.
