Chapter 6, Problem 6.28E
A soccer ball with mass 0.420 kg is initially moving with speed 2.00 m/s. A soccer player kicks the ball, exerting a constant force of magnitude 40.0 N in the same direction as the ball’s motion. Over what distance must the player’s foot be in contact with the ball to increase the ball’s speed to 6.00 m/s?

The net force that the four men together apply to the 325 kg bobsled is 93.484 N directed at 15 degrees below the horizontal. As they push, 60 N of kinetic friction opposes them.

You begin from rest at the bottom of the hill and travel a distance of 23 meters up the hill (measured along the incline), reaching a speed of 14 m/s. You have a mass of 60 kg. Determine the force the wind exerts on the parachute, assuming the force the wind exerts is parallel to the surface of the incline.
