Unformatted text preview:  work – kinetic energy theorem a m F = ∑ Example Problem , In an amusement park ride, passengers stand inside a 5.0m diameter hollow steel cylinder with their backs against the wall. The cylinder begins to rotate about a vertical axis. Then the floor on which the passengers are standing suddenly drops away. If all goes well, the passengers will “stick” to the wall and not slide down. Clothing has a static coefficient of friction between 0.60 and 1.0 and a kinetic coefficient between 0.40 and 0.70. A sign at the entrance says “No children under 30 kg allowed.” What is the minimum speed for which the ride is safe to ride? Example Problem 3.78 , As two boats approach the marina, the velocity of boat 1 relative to boat 2 is 2.15 m/s in a direction 47.0° east of north. If boat 1 has a velocity that is 0.775 m/s due north, what is the velocity (magnitude and direction) of boat 2?...
