Hello I have 2 problem for homework. I just started physics so these problems are probably quite easy however i was not at school today and was not taught how to do them. I don't even know wher to begin so any help would be great. Anyway the problems are:(adsbygoogle = window.adsbygoogle || []).push({});

1) Train A leaves Atlanta, heading towards Philladelphia, at a constant 92km/hr. Train B leaves Philadelphia at the same time, heading towards Atlanta, at a constant 58 km/hr. The two cities are 1250 km apart, and the tracks are strait. Find how long it takes for train a to get to Philly, How long after train A leaves do the two trains pass each other, and how far from atlanta do the two trains pass each other?

2)An elf shoots an arrow at a retreating orc. The orc is running away at a constant 16.8 m/s, and the arrow leaves the bow at a constant 32.4 m/s. If the orc is 42m away from the elf when the arrow is fired find how far away from the elf the aroow hits the orc, and how long is the arrow in the air for.

Thanks for your time guys.
