A car starts from rest and covers a distance of 40 m in 10 s. Calculate the magnitude of its acceleration.
A
3.20 ms\(^{-2}\)
B
0.25 ms\(^{-2}\)
C
0.80 ms\(^{-2}\)
D
4.00 ms\(^{-2}\)
correct option: c
S = ut + \(\frac{1}{2}\)at\(^2\)
40 = 0 x 10 + \(\frac{1}{2}\)a x 10\(^2\)
50a = 40
a = \(\frac{40}{50}\)
a = 0.8m/s\(^2\)
