Question

Abus of starting from rest moves with uniform acceleration of 0.1 ms for 2 minutes. Find (a) the speed acquired (b) the distance travelled.

Answer 1

Whenever a body starts from rest then its initial velocity becomes zero.

a = 0. 1 ms-²

t = 2 min = 120 s

a). For velocity,

v = u + at

v = 0 + 0.1 x 120

v = 12 ms-¹

b). For Distance,

S = ut + 1/2 at²

S = 0 + 1/2 x 0.1 x 120 x 120

S = 720 m
