Answer:

Time taken = 2.444sec

Step-by-step explanation:

Greetings !

Given values :-

  • Final velocity (Vf) =44km/hr =12.22m/s
  • Initial velocity (Vi) = 0m/s
  • Acceleration (a)= 5m/s²

Required values:-

  • Time taken (t) =?

Solution/ work-out:-

Firstly change the km/hr value to m/s

Then, recall the Velocity-Time Equation:


vf = vi \: + at

substitute known variables into the equation


(12.22) = (0) + (5)t

Solve for time


t = 2.444sec

Hope it helps!!
