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