Chapter 6, Problem 5RQ
- 5. A 1-kilogram mass has just been dropped from the roof of a building. I need to catch it after it has fallen exactly 100 meters. If I weight 80 kilograms and start running at 7 meters per second as soon as the object is released, how far away can I stand and still catch the object?

This attraction is a single-person roller coaster ride that has a 25.0 m drop followed by a collision with a plunger attached to a large spring that brings the ride to rest. The plunger/spring mechanism is composed of a large spring with a mass of 62.5 kg made of pure iron..The cart has a mass of 75.0 kg and starts at rest from the top of the track. To determine the total mass of the cart during the ride you must add your mass to the system. As the cart moves down the track it has been determined that friction in the wheels and axles results in the production of 12750 J of thermal and sound energy combined. The plunger/piston at the bottom of the device has been designed to stop the cart with a maximum acceleration of 5.00 g’s (i.e. 49.0 m/s2). What is your approximate mass in kilograms?
