Question

A body starts from rest and travels for t second with uniform acceleration of 2 m/s². If the displacement made by it is 16 m, the time of travel t is (a) 4 s. (b) 3 s. (c) 6 s. (d) 8 s​

Answer 1

Answer:

(a) 4 s

Explanation:

s= ut + 1/2 at²

16= 0 + 1/2 × 2 ×t²

16= t²

thus t=4

time of travel is 4 seconds
