Mitch throws a 100-g lump of clay at a 200-g target, which is at rest on a horizontal surface. After impact, the target, including the attached clay, slides 2.1 m before stopping. If the coefficient of friction is µ = 0.50, find the speed of the clay before impact
a. 4.5 m/s
c. 27 m/s
b. 14 m/s
d. 36 m/s
B

The following figures show a top view of Earth, sunlight, and six different positions of the Moon as it orbits Earth. Note that the distances shown are not drawn to scale. Rank each of the six lunar positions from left to right based on the amount of the Moon’s illuminated surface that is visible from Earth, from greatest to least. (If two diagrams have an equal amount of illumination as seen from Earth, put one on top of the other.)
