Two forces F1 and F2 are applied to a plank that supports a body of mass m, as shown in the figure. The distances between these forces and the body of mass m are L1 and L2, respectively. A. The values of F1 and F2 in static equilibrium depend on the choice of the axis of rotation.
B. In static equilibrium F1 = F2 for any values of L1 and L2.
C. The value of the sum (F1+ F2) that corresponds to static equilibrium is indepdendent of L1 and L2.
D. In static equilibrium, if L1 > L2, then F1 > F2.

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

The temperature in gavin's oven is a sinusoidal function of time. gavin sets his oven so that it has a maximum temperature of 280°f and a minimum temperature of 240°. once the temperature hits 280°, it takes 20 minutes before it is 280° again. gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 270°. he puts the cake into the oven when it is at 260° and rising. how long will gavin need to leave the cake in the oven? (round your answer to the nearest minute.)
