- 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 (MY MASS IS 55KG). 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…With fuel prices for combustible engine automobiles increasing, researchers and manufacturers have given more attention to the concept of an ultralight car. Using carbon composites, lighter steels and plastics, a fuel-efficient car can be manufactured at 540 kg. How much less does an ultralight car weigh compared to a 1450-kg Honda Accord (2007)?1. Calculate the location of center of mass of the system of 4 point masses as shown in the Figure. 4 kg 2 kg 5 m 4 m 4 m/ 8 kg 5m 6 kg

- 50 300g 10 10 25 cm 3) A kinetic sculpture consists of two rods of negligible mass, each suspended 10 cm from their ends. The longer rod has a length of 50 cm and the shorter has a length of 25 cm. If the square mass is 300 g, then what must the triangular mass and circular masses be to achieve equilibrium?35. A certain ping-pong ball has mass of 2.4 g and a terminal speed of 10.0 m/s as it falls through air. Suppose the same type of ping-pong ball is then filled with water such that it has a new mass of 21.6 g and it is dropped through the air. (a) Determine the acceleration of the water-filled ball as it falls at 10.0 m/s through the air. (b) Determine the terminal speed of the water-filled ball assuming that the air resistance is proportional to the square of the speed.15
