Question

write a short statement that expresses a possible function between the given variables. grade of hill, speed of sled

a. if you are coasting down a hill on a sled, the wider the hill, the slower you will coast.
b. if you are coasting down a hill on a sled, the steeper the hill, the slower you will coast.
c. if you are coasting down a hill on a sled, the narrower the hill, the faster you will coast.
d. if you are coasting down a hill on a sled, the steeper the hill, the faster you will coast.

Explanation:

The steeper the grade of a hill, the greater the gravitational - force component pulling the sled downwards, resulting in a faster speed. Width or narrowness of the hill is not directly related to the speed of the sled in terms of the force causing the motion.

Answer:

D. If you are coasting down a hill on a sled, the steeper the hill, the faster you will coast.
