When you reach Point Park, it's time to take the elevator up to class Let's say someone left a big spring on the floor of the elevator, and you have to step on it to fit in and let the doors close. The elevator accelerates upward at 3.0 m/s2. The spring constant is 2.5 Times 10^3 N/m. By how much is the spring compressed? You can use your own mass for this problem, or if you prefer, say it's around 60 kg.
