Question

a body is coming down an inclined plane with an acceleration òf 1M per sec. If it start from rest find the time after which it's velocity become 5 metre per second

Answer 1

Hi.

Here is the answer---

__________________

Given---

Acceleration = 1 m/s²
Initial Velocity = 0 [Since the Body starts from the rest]
Final Velocity = 5 m/s.

Using the formula,
 
          $a = \frac{v - u}{t}$
               1 = (5 - 0)t
               t = 5 seconds.

Thus, the time taken is 5 seconds.
