The coefficient of friction between the wheels of Yamaha motorcycle and the dry pavement is 0.79. An animal walks out into the road, causing a motorcyclist to slam on the brakes. The wheels stop turning, but the tires skid along the road, causing intense friction and heat. Determine the magnitude (positive) of the acceleration which the 217-kg motorcycle experiences while skidding to a stop. The mass includes the rider. Answer: m/s/s (or m/s²)
A hockey puck with mass 0.166 kg is pushed across the ice with a constant force of 0.89 N. The coefficient of kinetic friction between the puck and the ice is 0.22. After a distance of 2.6 m, what is the puck's speed in m/s?
A 40.4-kg skater is standing at rest in front of a wall. By pushing against the wall she propels herself backward with a velocity of -1.80 m/s. Her hands are in contact with the wall for 0.945 s. Ignore friction and wind resistance. Find the average force she exerts on the wall (which has the same magnitude, but opposite direction, as the force that the wall applies to her). Note that this force has direction, which you should indicate with the sign of your answer. Number i Units
As rock climbers ascend El Capitan over the course of 2 or 3 days, they have to bring all their food, water and camping equipment with them. All of this gear gets put in a large heavy duty bag and is hauled up after each section (called a pitch) that they climb. Climbers will generally climb a 50m pitch then stop and set up a pulley system to haul up the bag. If the rope has a mass of 0.05 kg per meter, the bag of gear has a mass 20kg and the rope is 50m long, how much work (in N-m) is required to pull up all the rope plus the haul bag?
