A 24N force acts on a body such that it changes its velocity from 5m/s to 9m/s in 2 secs.If the body is travelling in a straight line, calculate the distance covered in the period.
-
A.
22m -
B.
18m -
C.
14m -
D.
10m
Correct Answer: Option C
Explanation
(a = frac{v – u}{t} = frac{9 – 5}{2} = 2 ms^{-2})
(s = ut + frac{1}{2}at^{2} = 5(2) + frac{1}{2}(2 times 2^{2}))
= (14m)
