A car with an initial speed of 6.5 m/s accelerates at a uniform rate of 0.92 m/s^2 for 3.6 s. What is the final speed and the displacement of the car during this time?

Use the equations of motion, Luke!

Explanation:

S=ut+(1/2)at^2

S=6.5+(1/2)(0.92)(3.6^2)

S=12.46

v^2-u^2=2aS

v^2-(6.5)^2 color(white)("d")=color(white)("d")2(0.92)(12.46)

v^2=2(0.92)(12.46)-(6.5)^2

v=4.39
