प्रश्न
A body starts from rest with uniform acceleration 2 m s-2. Find the distance covered by the body in 2 s.

उत्तर
Initial velocity u = 0
Acceleration a = 2 m/s2
Time t = 2 s
Let 'S' be the distance covered.
Using the second equation of motion,
S = ut + (1/2) at2
S = 0 + (1/2) (2) (2) 2
S = 4 m
