- A cyclist coasts up a 10.0 degree slope, traveling 20.0 m along the road to the top of the hill. If the cyclist’s ini- tial speed is 9.00 m/s, what is the final speed? Ignore friction and air resistance1. I ran a computer simulation of a ball bearing (steel sphere, about 5 mm in diameter) falling under the force of gravity through (1) water and (2) purified honey. The downward velocity of the ball bearing (normalized to unity; "AU" = arbitrary units) is plotted against time below. (a) Which curve is the simulation of the ball bearing falling through water? (b) Which curve is the simulation of the BB falling through honey? (c) Draw and label a curve that represents what the velocity-vs.-time profile might be if the BB were falling through air.

Therefore all answers will have 3 significant digits. A fisher pulls a sled of fish along a flat horizontal surface. They are travelling forward at a constant velocity. The sled and the fish have a combined mass of 32.4 kg. These sled and the fish can be treated as one object for the problem. There are four forces acting on the sled of fish: There is a force of gravity [down]. There is a normal force [up]. There is a force of kinetic friction [backwards]. The fisher pulls with an angled forward force of 43.2 N [33.6 degrees above the horizontal]. Calculate the coefficient of kinetic friction between the sled and the ground. Hint: constant velocity means that the net force is zero.
