Question

Blake and Drew are playing horseshoes. Blake takes the first turn, and his horseshoe lands three-fourths of the way to the target. Drew takes the next turn, and his horseshoe lands past the target. Which statement best explains the results?
A. Drew used a horseshoe with more mass and threw with the same force as Blake.
B. Drew used a horseshoe with more mass and threw with less force than Blake.
C. The horseshoes have the same mass, but Drew threw with less force than Blake.
D. The horseshoes have the same mass, but Drew threw with more force than Blake.

Answer 1

D.

Because Drew's horseshoe went farther, he must have given it a greater launch speed. With the same mass, throwing with more force produces a higher speed and thus a longer travel; making the horseshoe heavier (A or B) would reduce acceleration and speed for the same or less force, so those can't explain going past the target.
