Use these equations to solve the following problems

xo= initial position
x= final position

vo = initial velocity
v = final velocity

The bar over the v means average velocity.

A marble is dropped from 2.5 m and hits the ground in 0.71 s. What is the final velocity before it hits the ground? (Hint: what is its initial velocity?)

An Olympic-class sprinter starts a race with an acceleration of 4.50 m/s2. What is her speed 2.40 s later?

A car skids to a stop to try to avoid hitting a deer. The car skids 21 m in 2.3 s. How fast was the car originally going?

This was across the street from my brother's house last week.

If a moose can accelerate at 2.1 m/s2 from rest, how much time will it take for it to accelerate to a speed of 4 km/h?

A fireworks shell is accelerated from rest to a velocity of 65.0 m/s over a distance of 0.250 m.

How long did the acceleration last?

Calculate the acceleration

When you try to stop your car in an emergency, there is some time before you can react. Your car is going 25 m/s and your reaction time is 0.20 s, then after you hit your brakes it accelerates at - 9.5 m/s2. How far will your car travel before it stops?
