1. A wheel that initially spins at 2 revolutions/sec is brakeduniformly to a stop in ½ second. How many revolutions does thewheel make while coming to a stop?

2. If a person has a speed of 3 m/s and is located 2-m from theaxis of rotation of a merry-go-round, what is the person's angularvelocity?

3. A hockey player with a mass of 46.0 kg is traveling due eastwith a speed of 2.95 m/s. A second hockey player with a mass of66.0 kg is moving due south with a speed of 6.95 m/s. They collideand hold on to each other after the collision. Find the directionthey travel after the collision given as an angle measured south ofeast.

4. The Seattle ferris wheel has a radius of 11-m and travelswith an angular velocity of 1.5 rad/sec. What is the normal force(apparent weight) acting on a 57-kg person at the bottom of theswing?

5. A 65 kg snowboarder travels down a 37° incline at 6.2 m/s. Inorder to stop before hitting a tree, the snowboarder quickly turnstheir board to increase the coefficient of kinetic friction to 1.9.What is the normal force between the snowboarder and theground?

6. A 65 kg snowboarder travels down a 37° incline at 6.2 m/s. Inorder to stop before hitting a tree, the snowboarder quickly turnstheir board to increase the coefficient of kinetic friction to 1.9.What is the friction force between the snowboarder and theground?

7. A 65 kg snowboarder travels down a 37° incline at 6.2 m/s. Inorder to stop before hitting a tree, the snowboarder quickly turnstheir board to increase the coefficient of kinetic friction to 1.9.How far does the snowboarder slide before stopping? Assume the paththe snowboarder takes is straight down the slope.
