You decide to relive your childhood years, playing with toy cars and trucks, by launching your real car down the road using a large spring. Your car has a mass of 1500kg and a coefficient of friction of 0.050 with the ground. You purchase a 2.0m long spring for the job, and compress it until it is 0.75m long.

You measure the speed of your car as it leaves the spring to be 22m/s. What is the spring constant of the spring?
