Question

What is the acceleration if the body starts from rest and travels a distance of ‘s’ m in 2 seconds? (a) (23s)m/s^2 (b) (32s) m/s^2 (c) (13s) m/s^2 (d) (12s) m/s^2 .

Answer 1

Given:

Initial velocity u = 0

Time taken t = 2 s

Distance travelled = 's' m

To Find:

Acceleration 'a'

Solution:

Using the equation of motion in kinematics,

$s = ut + \frac{a {t}^{2} }{2}$

$s = 0 + \frac{ {2}^{2}.a }{2}$

$s = 2a$

$a = \frac{s}{2}$

a = 0.5 m/s^2

The acceleration of the body is 0.5s m/s^2.

Answer 2

(8/2 s) m/s²
