Question

Starting from rest a car travels a distance 60km at a uniform acceleration of 2ms-2. How much time it takes?

Answer 1

t = 30000 seconds

Step-by-step explanation:

Given that,

Initial velocity of the car, u = 0

Final velocity of the car, v = 60 km = 60000 m

The acceleration of the car, a = 2 m/s²

W need to find the time taken by the car. The acceleration of the object is given by :

`a=(v-u)/(t)`

or

`t=(v-u)/(a)\\\\t=(60000-0)/(2)\\\\t=30000\ s`

So, the required time is 30000 seconds.
