Answer:

[tex]\huge\boxed{\sf a = 100\ kmh^{-2}}[/tex]

Explanation:

Given Data:

Distance = 200 km

Initial Velocity = Vi = 0 m/s

Time = 2 hours

Required:

Acceleration = a = ?

Formula:

2nd equation of motion

Solution:

[tex]\displaystyle S = Vit+\frac{1}{2} at^2\\\\200 = (0)(2)+\frac{1}{2} a(2)^2\\\\200 = \frac{1}{2} a (4)\\\\200 = 2a\\\\Divide\ both\ sides\ by\ 2\\\\200/2 = a\\\\a = 100\ kmh^{-2}\\\\\rule[225]{225}{2}[/tex]

Hope this helped!
