Question

a body starts from rest and moves with a uniform acceleration of 2 metre per second square what will be its velocity and displacement at end of 10 seconds​

Answer 1

Explanation:

The velocity = (a) X (t) = ( 2 m/s^2 ) X (5 seconds ) = 10 m/s

From the Calculus, the integration of the above equation with zero initial condiitions yields:

Displacement = 1/2 (a) t^2 = (1/2) X (2 m/s^2 ) (5 seconds)^2 = 25 m.

NB that the units are operated on in the same way as the magnitudes to the units of the answer.
