A body starts from rest and moves in a straight line with uniform acceleration of (5 ms^{-2}). How far, in metres, does it go in 10 seconds?
-
A.
50 m -
B.
250 m -
C.
350 m -
D.
500 m
Correct Answer: Option B
Explanation
(s = ut + frac{1}{2} at^{2})
(u = 0, t = 10 secs, a = 5 ms^{-2})
(s = 0 + frac{1}{2} 5 times 10^{2})
(s = 250 m)
