Question

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

Answer 1

Answer:

t = 30000  seconds

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 :

$a=\dfrac{v-u}{t}$

or

$t=\dfrac{v-u}{a}\\\\t=\dfrac{60000-0}{2}\\\\t=30000\ s$

So, the required time is 30000  seconds.
