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

The correct answer is C. 36m

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
