Dennis is riding a bike at a speed of 10 m/s when he sees someone not paying attention walk out in front of him. He hits the brakes and slows to a speed of 2 m/s, so he doesn't collide with the other person. Dennis and his bike have a combined mass of 92 kg. How much work was done to slow them down?

A block of mass 0.500 kg is pushed against a horizon-tal spring of negligible mass until the spring is compressed a distance x (Fig. P8.65). The force constant of the spring is 450 N/m. When it is released, the block travels along a frictionless, horizontal surface to point , the bottom of a vertical circular track of radius R = 1.00 m, and continues to move up the track. The blocks speed at the bottom of the track is v = 12.0 m/s, and the block experiences an average friction force of 7.00 N while sliding up the track. (a) What is x? (b) If the block were to reach the top of the track, what would be its speed at that point? (c) Does the block actually reach the top of the track, or does it fall off before reaching the top?
