$A body starts from rest and moves with a uniform acceleration of a = 1 m/s^{2} . What is the distance covered by the body in t = 4 s ?$

A. $4 m$
B. $8 m$
C. $12 m$
D. $16 m$

Show correct answer & step-by-step solution

Correct answer: B — $8 m$

Solution

Using the second equation of motion, s = u t + 0.5 a t^{2} . With u = 0, a = 1 m/s^{2}, and t = 4 s, we get s = 0 + 0.5 (1) (4)^{2} = 8 m .
