- You have been chosen as the test subject for the newest attraction at Disney. This attraction is a single-person roller coaster ride that has a 25.0 m drop followed by a plunger/piston device that brings the ride to rest. The plunger/piston is connected to a cylinder that contains 250 kg of water. 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. As the cart moves down the track it has been determined that friction in the wheels and axles results in the production of 2750 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). QUESTION: The remaining kinetic energy of the cart is removed as work is done pushing in the plunger/piston and compressing the water inside the cylinder. Use the work equation to determine the displacement of the plunger/piston.…1. Determine whether the statements below are true or false: a. Two carts move in the same direction along a frictionless track, each acted upon by the same constant impulse. If Cart 1 has the twice the mass of Cart 2, then Cart 2 will have the greater change in linear momentum. b. Any force component that causes a centripetal acceleration cannot change the translational kinetic energy of the object. A person's mechanical stability can be increased by lowering one's center of c. mass (such as when one bends their knees).You have been chosen as the test subject for the newest attraction at Disney.
