A cop claims you passed him at more than 60mph (27.8m/s), 200 meters from a red light that changed green. You drive a 1970 VW beetle convertible that accelerates at a maximum of 1.5 m/s2. When you go before the traffic court, do you beat the ticket? Please show how you did it :)

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.)
