A football coach sits on a sled while two of his players build their strength by dragging the sledacross the field with ropes. The friction force on the sled is 1400 N and the angle between the two ropes is 50 ●.Assume both players pull with the same force. How hard must each player pull to drag the coach at a steady 2.0m/s?

Given: The frictional force on the sled is 1400 N. The angle between the two ropes is 50°.…

Seth wants to drag a 20.0 kg. sled over a flat field. He pulls on the rope horizontally, and the coefficient of friction is 0.60. With what force must Seth pull to keep the sled moving with a constant velocity? With what force must Seth pull to give the sled an acceleration of 2.0 m/s2?
An 80 kg log is sliding along a flat section of ground at constant velocity with a coefficient of kinetic friction of 0.33. A truck is dragging the log by using a cable that runs from a winch on the truck to the end of the log. The cable pulls at an angle of 30 degrees above the horizontal. What is the tension of the cable?
while looking for a set of new tires for your car, you find an advertisement that offers two brands of tires, brand x and brand y, at the same price. Brand x has a coefficient of friction on dry pavement of .90 and on wet pavement of .15. Brand y has a coefficient of friction on dry pavement of .88 and on wet pavement of .45. If you live in an area with high levels of precipitation, which tires would give you better service? Explain.
