2. Bear takes his skateboard on a track. He begins from rest at point A. The track he travels on is frictionless, except for a rough patch between points B and C, where the coefficient of kinetic friction is 0.15. If he runs into a spring (spring constant 300 N/m) at the end of the track, how far does the spring compress? Bear and his skateboard have a combined mass of 1.25 kg. (Use energy methods to solve this problem.) 3.8 m A B 2.0 m 300 N/m ooooo

A 7.44-kg particle is subject to a net force that varies with position as shown in the figure. The particle starts from rest at x = 0. Fx (N) 3 2 2 4 6 8 10 12 14 16 What is its speed at the following positions? (a) x = 5.00 m 154.32 X Can you determine the kinetic energy of the particle at x = 5.00 m from the given graph? m/s (b) x = 10.0 m 154.33 x (m) X You appear to have added your result from part (a) to a speed calculated from the work done between 5 and 10 m. This doesn't work; you must calculate the work done over the entire 10 m distance. m/s (c) x = 15.0 m 151.31 X The force is positive throughout the entire interval. Does it make sense that the speed would decrease m/s

A mouse is on a crazy roller coaster which has five distinct phases. The mouse in his roller coaster car has a mass of 6 kg. The mouse starts the coaster by being pulled back 0.2 m into a spring with a spring constant of 1890 N/m. How much elastic potential energy does the mouse have as he starts his ride? After the spring is released, the mouse travels over the first hill, effectively coming to rest at the top. Calculate the height of the first hill? He then speeds into a valley. At the bottom of the valley 3 J of energy is lost due to friction. What is his total remaining energy after he travels through the valley? The mouse then travels over a 0.10 m hill. How fast is the mouse traveling over the hill at point D? The mouse finally makes it to the final phase of the ride, where he will race along at ground level. How fast is he traveling at point E?
