...what is the answer and y? 1.) Your suitcase has not slid all the way down the slope and is going around at a constant speed on a circle (r = 11.0 m) as the carousel turns. The coefficient of static friction between the suitcase and the carousel is 0.620, and the angle ? in the drawing is 13.9 °. What is the minimum time required for your suitcase to go around once?
2) A person is riding a bicycle, and its wheels have an angular velocity of 13.3 rad/s. Then, the brakes are applied and the bike is brought to a uniform stop. During braking, the angular displacement of each wheel is 15.7 revolutions. (a) How much time does it take for the bike to come to rest? (b) What is the anguar acceleration (in rad/s2) of each wheel?
3) In San Francisco a very simple technique is used to turn around a cable car when it reaches the end of its route. The car rolls onto a turntable, which can rotate about a vertical axis through its center. Then, two people push perpendicularly on the car, one at each end, as in the figure. The turntable is rotated one-half of a revolution to turn the car around. If the length of the car is 7.39 m and each person pushes with a 185-N force, what is the magnitude of the net torque applied to the car?
4) A rotating door is made from four rectangular glass panes. The mass of each pane is 92.5 kg. A person pushes on the outer edge of one pane with a force of F = 107 N that is directed perpendicular to the pane. Determine the magnitude of the door's angular acceleration.
5)A bowling ball encounters a 0.760-m vertical rise on the way back to the ball rack. Ignore frictional losses and assume that the mass of the ball is distributed uniformly. The translational speed of the ball is 5.25 m/s at the bottom of the rise. Find the translational speed at the top.
