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

Answer:

Time taken = 2.444sec

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!!
