**Acceleration**

Have you been driving down an empty interstate? With an empty stretch of land for miles ahead, you begin to pick up speed. You end up going from 35 to 90 mph. How do you calculate your average uniform acceleration?

To calculate this you may use this formula

V_{f} = V_{i}+at

In this scenario assuming it took you ten minutes to increase your speed

90=35+a(600)

a=55/600

a=0.09 miles/sec

Your speed increased at 0.09 miles per second.

Creative Application:

1. What if your final speed was 200 mph?

2. Find another scenario in which you use V_{f} = V_{i}+at to calculate an answer with?
