Question

A particle moves along the X-axis as
x=u(t-2s)+a(t-2s)^2

(a) the initial velocity is u
(b) the acceleration is a
(c) the acceleration is 2a
(d) at t=2s the particle is at the origin

Answer 1

Hi! Is there a question here?

Answer 2

yeahh ...do u know it ..?

Answer 3

Your particle is simply undergoing a uniformly accelerated linear motion.

Obviously (d) is a correct statement.

The initial velocity is u-4a
The acceleration is 2a
At t=2s, the particle is at the origin.

Answer 4

Substituing t=2s into your equation... u get x = 0 ! :)

Answer 5

yes thank you very much ..!
