A particle moving with a velocity of 5m/s accelerates at 2m/s\(^2\). Find the distance it covers in 4 seconds.
- A. 16m
- B. 26m
- C. 36m
- D. 46m
Correct Answer: C. 36m
Explanation
from the equation of motion
u = 5m/s, a = 2m/s\(^2\), t = 4s
s = ut + \(\frac{1}{2} at^2\)
s = 5*4 + \(\frac{1}{2} 2*4^2\)
s = 20 + 16
s = 36m
