m = 325 kg h1 = 19.5 m h2 = 4.7 m A roller coaster car of mass m is rolling down the track, starting from rest, as shown in the figure. The initial height from the ground is h1 (Position-1), while the final height is h2 (Position-3). The system has no friction. What is the speed of the car when it reaches its final height (Position-3).

Taylore has a couch that she wants to move in Davidson Student Center's lounge, with mass 12.7 kg. The couch starts at rest. Taylore pushes with an 24.4 N force, and the object has a displacement of 11.2 m, directed 30.0° from the direction of the force. What is the final speed of the couch? Your Answer: Answer
A rocket with mass 7.00×103 kgkg is in a circular orbit of radius 7.50×106 mm around the earth. The rocket's engines fire for a period of time to increase that radius to 8.80×106 mm, with the orbit again circular. Part A What is the change in the rocket's kinetic energy? Does the kinetic energy increase or decrease? Express your answer with the appropriate units. Enter positive value if the kinetic energy increases and negative value if the kinetic energy decreases.
