Rodney and Dennis are gleaning (collecting) corn from a cornfield that is 3.33.3 miles long. Rodney starts on one end and is gleaning corn at a rate of 0.250.25 miles per hour. Dennis starts on the other end and is gleaning corn at a rate of 0.300.30 miles per hour. If they start at the same time and continue to work at the same rate, how long will it be before Rodney and Dennis meet?

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
