6. A roller coaster cart is pulled up the top of a hill 45 m high. The cart then moves over the crest at an average speed of 0.5 m/s before it plunges down to its lowest point, 5 m above the ground. From there, it climbs over a second hill only 15 m high. What is the cart's speed as it goes over the top of the second hill.
