An elevator whose mass is m = 400 kilograms is supported by a cable. a frictional force of f = 80 newtons is applied to the elevator as it moves. determine the tension t in the cable when the elevator is:
a.) stationary;
b.) moving upward while accelerating at 2.8 m/s2;
c.) moving upward with a constant velocity-magnitude of 5 m/s;
d.) accelerating downward at 2.8 m/s2 with velocity downward;
e.) moving downward with a constant velocity-magnitude of 5 m/s.

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.)
