Use the following Infomadon to answer queston 174 A 0.5-klogram block alldos al 20 m/s on a smooth frictionless surface toward a stationary sphere, with a mass of 20-kllograms, as shown below. A plot of the forca exerted on the block by the spharga a function of tlma is shown below. 17. Calculate the Impulse applied to the block by the sphere. Use the following Information to answer questions 18 & 19: The dlagram below shows three points on a roller coaster track. A car starts from rest at polnt X and travels along the track. Assume friction is negligible. 16 m Helght HERE X 18. Identify whether the car's gravitational potential energy increases, decreases, or stays the same as the car moves from point X to point Y. 19. The car has a mass of 600 kg. Calculate the gravitational potential energy of the car at its maximum height.
