Question

If a body travelling at initial velocity 5 m/sec but after 10 second its fibal velocity is 15 m/sec​

Answer 1

Explanation:

Let’s refer to the 4 basic kinematic equations of motion for constant acceleration (this is actually a lesson):

s = ut + ½ at^2

v^2 = u^2 + 2as

v = u + at

s = (u + v)t/2

where s is distance, u is initial velocity v is final velocity a is acceleration and t is time.

In this case, since we know u, v and t, the appropriate equation is:

v = u + at or 25 = 5 + 10a so a = (25 – 5)/10

a = 2m/s^2
