A body starts with an initial velocity 26 m/s and moves with a constant acceleration of 7 metre per seconds for 25 seconds. find the total distance moved in metres.​

Explanation:

Let’s review the 4 basic kinematic equations of motion for constant acceleration (this is a lesson, and you should commit these equations to memory):

s = ut + ½ at^2 …. (1)

v^2 = u^2 + 2as …. (2)

v = u + at …. (3)

s = (u + v)t/2 …. (4)

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

In this case, we have u = 26m/s, a = 7m/s^2, t = 25sec, and we want to know the distance, s

So we choose equation (1) s = ut + ½ at^2

s = 26(25) + ½(7)(25^2)

s = 650 + 2187.5

s = 2837.5m

The total distance covered is 2837.5m
