Question

A car starting from a particular position and moving with uneform acceleration attains a speed 50km/hour in 8 minutes. find it's acceleration.​

Answer 1

0.028m/s^2 is the acceleration of the car.

Explanation:

Given that,

The car starts from the rest position, so

u = 0

Velocity(v) = 50 km/hr or 50 * 5/18 = 13.88 m/s

Time(t) = 8 minutes * 60 = 480 seconds

Using motion's first equation,

v = u + at

13.88 = 0 + a (480)

a = 13.88/480

= 0.028 m/s^2

Thus, the acceleration of the car is 0.028m/s^2.
