Disregarding friction, a roller coaster with a vertical drop of 46 m will achieve a speed of about 30 m/s. If the height of the drop is doubled, how much the speed is going to be?
A 60.0 kg skier with an initial speed of 16.5 m/s coasts up a 2.50 m high rise as shown in the figure.
Find her final speed right at the top, in meters per second, given that the coefficient of friction between her skis and the snow is 0.35.

- Check Your Understanding You probably recall that, neglecting air resistance, if you throw a projectile straight up, the time ii takes to reach its maximum height equals the time it takes to fall from the maximum height back to the starting height.
