Photographers control the "blurring" in a picture by varying the shutter speed, i.e., the amount of time the film is exposed. A very sharp picture with little blurring implies which of the following:

a. the shutter speed is very fast.
b. the objects in the photograph are not moving.
c. both a. and b. are possible interpretations.
d. the camera is shaking.
e. the camera is out of focus.

A sports car and a moving van move at the same speed when they crash into a cement wall and stop equally quickly. The vehicle to have the greater force of impact will be

1) the sports car, 2) the van, 3) neither, for they experience equal forces of impact because 4) they are traveling at the same speed. 5) the van's momentum is much greater. 6) the sport car has a greater change in velocity upon impact. 7) they both have equal momentum.
