What is the acceleration of a car that starts at rest and achieves a final velocity of 33.5 m/s in a time of 12 seconds?

Sagot :

Variables we are given and that we know:

vi: initial velocity; vi = 0 m/s

vf: final velocity; vf = 33.5 m/s

t: time; t = 12 s

We need to find a: acceleration

We can use the formula:

vf = vi + a*t

Let's substitute the values we know:

33.5 = 0 + a*12

33.5 = 12a

Let's solve for a:

a = 33.5/12

a = 2.7917 m/s^2
