Suppose an unpowered go-cart (with a child rider) traveling at an initial speed of 5 m/s. Coast on a level road for about 50 m before coming to rest. If the cart and rider have a mass of 40 kg, about what force would you have to apply to keep the cart moving at a constant speed? Assume that the friction forces acting on the cart are approximately independent of its speed. (Hint: Use the “momentum requirement” to compute the magnitude of the total friction per drag force acting on the cart, then link this force to the force you must apply.)

A clever coyote uses rocket powered skates to try to catch a roadrunner. The mass of the coyote is 38.1 kg. If the coyote starts from rest, and accelerates to a final speed of 26 m/s in a distance of 2.4 m, how much thrust force did the rockets excert to get him to his final speed? Assume this thrust is constant over the 2.4 m.
A boy slides down a hill on a sled (total mass of 42 kg) and coasts onto a flat plain with a speed of 6.1 m/s. Friction between the sled and the snow exerts an average force of magnitude 39 N on the sled. How far (in m) does the sled travel before stopping? (Note: First, find the acceleration of the boy using Unit Two material, then use this to compute the distance using Unit One material.)
A child riding a bicycle has a total mass of 30.6 kg. The child approaches the top of a hill that is 27.9 m high 27.9 and is 86.8 m (ℓ) long at 12.1 m/s.

A ball of mass 2 kilograms is loaded into a spring gun which is pointed vertically upward. At t = 0 seconds, the spring gun exerts an upward force of 100 newtons for 1 second. Assuming a drag coefficient of 0.3 kilograms per second and drag proportional and against the velocity, give a second-order equation and initial conditions for vertical position y in meters of the ball that is initially at rest. Use g = 9.8 meters per second per second and assume the initial position is 0.
