Write a hypothesis for Part I of the lab, which is about the effect on an object being carried by a car, when the car experiences a sudden impact. Use the format of "if . . . then . . . because . . . ” and be sure to answer the lesson question "How can Newton's laws be experimentally verified?” specific to Newton’s first law.

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.)
