An object with an initial velocity of 5 m/s accelerates uniformly for 15 s.

(a) If the final velocity is 37 m/s, what is the acceleration?

4 answers

Vf=Vi+acceleration*time
solve for acceleration.
How far does the object travel during this time?
You need to memorize some formulas:

distance= Vi*time+ 1/2 * acceleration*time^2

or

distance=average velocity*time
=(1/2)(Vf+Vi)*time
