A Dangerous Ride. You and your exploration team are stuck on a steep slope in the Andes Mountains in Argentina. A deadly winter storm is approaching and you must get down the mountain before the storm hits. Your path leads you around an extremely slippery, horizontal curve with a diameter of 80.0 m and banked at an angle of 40.0° relative to the horizontal. You get the idea to unpack the toboggan that you have been using to haul supplies,...

The OntarioTech rowing team is moving along at a steady speed of 17.86 m/s. The cox issues an order to increase the rate of speed of the boat and the boat uniformly accelerates to reach a final speed of 41.1 m/s. If the boat traveled a distance of 53 m before reaching the final velocity, what was the boat’s acceleration over that distance? An airplane accelerates down a runway at 13.7 m/s2 for 12.1 s until it finally lifts off...

A motorcycle daredevil plans to ride up a 2.1 m high 23.5 degree ramp, sail across a 8 m wide pool filled with hungry crocodiles, and land at ground level on the other side. He has done this stunt many times and approaches it with confidence. Unfortunately, the motorcycle engine dies just as he starts up the ramp. He is going 12 m/s at that instant, and the rolling friction of his rubber tires (coefficient 0.02) is not negligible. Does...
