Question

An object originally at rest, is accelerated uniformly along a straight line to a speed of 8m/s in 2s. What is the acceleration of the object?​

Answer 1

4m/s²

Step-by-step explanation:

Initial velocity (u) = 0 m/s

Final velocity (v) = 8 m/s

Time taken (t) = 2 sec

Acceleration (a) = ?

We know

`a = (v - u)/(t) \\ = (8 - 0)/(2) \\ = (8)/(2) \\ = 4 \: m |s ^(2)`

Hope it will help :)
