Answer 1

Explanation:

The initial velocity u =36 km/h=10 m/sthe Final velocity v =72 Km/h = 20 m/sThe time period t = 10 s using first equation of motionv – u = atwherev is the final velocityu is the initial velocitya is the accelerationt is the time period putting the value of v,u,t in the equation, we get20 -10 =a ×10a = 1 m/s2
