Question

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?

Answer 1

Vf=Vi+acceleration*time
solve for acceleration.

Answer 2

How far does the object travel during this time?

Answer 3

You need to memorize some formulas:


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

or

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