You devise a wind-up car powered by a spring for trips to the grocery store. The car has an inertia of 600 kgkg and is 4.9 mm long. It should be able to accelerate from rest to 29 m/sm/s at least 50 times before the spring needs winding. The spring runs the length of the car, and a full winding compresses it to half this length.
In order to meet the acceleration requirement, what must the value of the spring constant be?
