Question

A body is accelerating at a constant rate of 10 m/s2 .if the body starts from rest. How much distance will it cover in 2s.

Answer 1

v = u + at

    =  0 + 10 * 2

    = 20


Hope this helps!

Answer 2

a = 10m/s²
u = 0m/s
t = 2 sec

using second equation of motion ,
S = ut +1/2at²
s = 0(2) + 1/2 × 10 × (2)²
s = 0+5×4
=> s = 20 m


hope this helps
