Design criteria are the goals the design must achieve. In this case, the bumper must reduce the force exerted in a
collision using the setup. The bumper should not add a lot of mass to the car. To lower the mass, the bumper must
contain mainly empty space. To better compare bumpers, each prototype must be the same size: 6 inches long. 2 inches
high, and 2 inches deep. The constraint for the bumper design is that you must use materials you have on hand.
Using your knowledge about collisions and Newton's laws, brainstorm ideas about two different bumpers that will meet
the criteria and the constraint. Draw your two best ideas here. Describe your ideas using text boxes.

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?

The average time that it takes for the car to travel the first 0.25m is s. the average time to travel just between 0.25 m and 0.50 m is s. given the time taken to travel the second 0.25 m section, the velocity would be m/s.
