# A roller coaster accelerates from an initial velocity of 6.0 m/s to a final velocity of 70 m/s over 4 seconds. What's the acceleration?

## Question

## Solution 1

To find the acceleration, we can use the formula for acceleration which is:

a = (v_f - v_i) / t

where: a is acceleration, v_f is the final velocity, v_i is the initial velocity, and t is time.

Given in the problem: v_f = 70 m/s, v_i = 6.0 m/s, and t = 4 seconds.
