Question

How long will it take a car to go from a complete stop to 44 km/hr if they are accelerating

at 5m/s²?

Answer 1

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!!
