Sliding on the Ice

In the winter sport of curling, players give a 20 kg stone a push across a sheet of ice. The stone moves approximately 40 m before coming to rest. The final position of the stone, in principle, only depends on the initial speed at which it is launched and the force of friction between the ice and the stone, but team members can use brooms to sweep the ice in front of the stone to adjust its speed and trajectory a bit; they must do this without touching the stone. Judicious sweeping can lengthen the travel of the stone by 3m.

77. A curler pushes a stone to a speed of 3.0 m/s over a time of 2.0 s. Ignoring the force of friction, how much force must the curler apply to the stone to bring it up to speed?

A. 3.0 N

B. 15 N

C. 30 N

D. 150 N

A 2000kg car travelling at 10.0m/s collides with a 3000kg car that is initially a rest at a stoplight. The cars stick together and move 2.00m before friction cause them to stop. Determine the coefficient of kinetic friction between the cars and the road, assuming that the negative acceleration is constant and all wheels of both cars lock at the time of impact

3. In the Circular Motion Video Lab activity, we followed a stopper on a turntable that spins faster with time until eventually the stopper slipped and flew off the turntable. Assume the speed of the stopper was increasing at a rate of 2 m/s² and it had a speed of 0.8 m/s and it was a distance of 12 cm from the center of the turntable just before it slipped. a. Draw the free body diagram for the stopper using the view from above to show the horizontal forces acting on the stopper. b. What is the coefficient of static friction between the stopper and the turntable? view from above c. What was the angle between the acceleration and velocity vectors when the stopper slipped?

16. Running without friction is impossible. In fact, to maximize your acceleration, you need to maximize the static friction between your shoes and the floor. a) Explain why static friction is necessary for running or walking. requirement, employees' shoes must have a coefficient of static friction of 0.5 or more on a specified tile surface. In an emergency, what is the minimum time interval in which a postal worker starting from rest can move a distance of 3 m on the tile surface? c) A typical athletic shoe has a coefficient of static friction of 0.8 when used on a running track. What is the minimum time interval in which an athlete starting from rest can move a distance of 100 m on a running track? b) To meet a U.S. Postal Service
