Daredevil Dave climbs into his stunt pod and uses a very large spring (k = 18,000 N/m) to launch himself from rest along a frictionless track (see side view diagram). The pod, with total mass M... 85.0 kg, is used to compress the spring by an amount 1.50 m before being released. NOTE: For all parts of this problem, consider the motion of the pod from the moment that the compressed spring is released until the moment when Dave's pod reaches its highest point (after leaving the right end of the ramp). Compressed spring Dave's pod launched vertically from end of ramp M... = 85.0 kg 9.0 m B. What is the speed of Dave's stunt pod when it passes through point Q. located 9.0 m below the point of launch (see diagram). Clearly show all work.
