Acceleration

A body starts...

Question

A body starts from rest and requires a velocity $10 m s^{- 1}$ in 2s.Find the acceleration.

Open in App

Solution

Given
initial velocity (u)=0
final velocity (v)= $\frac{10 m}{s}$
Time = 2sec

so
applying $v = u + a \times t$
$10 = a \times 2$
a=accelaration= $\frac{5 m}{s e c^{2}}$
