A car accelerates from rest at - 2.40 m/s2. (Include the sign in your answers.) (a) What is the velocity at the end of 3.6 s?

Velocity at the end of 3.6 s is - 8.64 m/s

Explanation:

We have equation of motion v = u + at

Initial velocity, u 0 m/s

Final velocity, v = ?

Time, t = 3.6 s

Acceleration, a = - 2.40 m/s²

Substituting

v = u + at

v = 0 + - 2.40 x 3.6

v = - 8.64 m/s

Velocity at the end of 3.6 s is - 8.64 m/s
