You are driving your car along a level road at a constant speed when you see a bear in the distance begin to move out onto the road ahead of you. From the moment you first see the bear to when you can react and slam on the brakes, you travel 30.5 m down the road. Assume the brakes apply a roughly constant braking force to the car due to the friction from the road. The mass of you and the car is 1650 kg and it takes you 15.7 s from the moment you slam on the brakes to come to a complete stop. If the total distance you travel down the road from when you initially see the bear to when you finally come to rest is 275 m,       a)   How fast were you moving when you initially saw the bear? b)   How long, from the moment you first saw the bear, did it take you to react before slamming on the brakes (reaction time)? c)   What was the acceleration of the car as it was braking? d)   What braking force did the friction from the road apply to the car?

Bob and Sally are on a merry-go-round of radius which is rotating with a constant angular speed. If Bob is halfway from the center of the merry-go-round at , while Sally is at its edge a distance  from its center, which of the following statements is true?

Extra credit but important!  Researchers can readily extract DNA from one organism and merge that DNA into another organism, applying genetic engineering as a possible cure to cancer or muscular dystrophy and other diseases. The scientific method can test a hypothesis to determine if this approach is morally right or wrong.
