A car takes off from rest and covers a distance of 80m on a straight road in 10s. Calculate the magnitude of its acceleration
-
A.
1.25ms-2 -
B.
1.60ms-2 -
C.
4.00ms-2 -
D.
8.00ms-2
Correct Answer: Option B
Explanation
s = (ut + frac{1}{2}at^2)
80 = 0 x 10 + (frac{1}{2}) x a x 102
a = (frac{80}{50} = 1.6ms^2)
