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?

Vf=Vi+acceleration*time
solve for acceleration.
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
distance= Vi*time+ 1/2 * acceleration*time^2
or
distance=average velocity*time
=(1/2)(Vf+Vi)*time
