(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Sorry to bother, but I was working through some homework I haven't done (I put a * next to ones I didn't get and I just wanted to post them because I have no idea how to do them):

1. If you are on a bus that is traveling along a straight, level road at 100 km/h, you are traveling at 100 km/h too.

(a) If you hold an apple over your head, how fast is it moving relative to the road? Relative to you?

(b) If you drop the apple, does it still have the same horizontal motion?

2. What is the advantage of the large flat sole on the foot of an elephant? Why must the small foot (hoof) of an antelope be so hard?

2. Relevant equations

Zip! These be word problems.

3. The attempt at a solution

1. (a) 100 km/h relative to road, 0 km/h relative to you

(b) I don't know about this one.

2. This doesn't even seem like a Newton's Law problem (hardness? what the?)
