Question

A body attains a velocity of 25ms-1 in 2s with an acceleration of 4ms-2 find the displacement of the body

Answer 1

Use the formula
$s = ut + \frac{1}{2} a {t}^{2}$
Given u=25m/s
a=4m/s^2
t=2s
You'll get
s=58m.

Answer 2

Given,
initial velocity(u)=25m/s
time(t)=2sec
acceleration(a)=4m/s^2
So,s=ut+1/2at^2
S=25×2 + 1/2×4×2×2
Displacemnt =58m
