Hello everyone! I'm a senior in high school, new to the forums and need some help, mainly because I got a 59% on my first test :uhh:(adsbygoogle = window.adsbygoogle || []).push({});

I am a physics newbie and need a lot of help

For starters, I have a couple questions here that i would like help with.

1)A photographer in a helicopter ascending vertically at a constant rate of 12.5m/s accidentally drops a camera out the window when the helicopter is 60m above the ground. (A) How long will it take the camera to hit the ground? (B) What will its speed when it hits?

-Is the 12.5m/s INITIAL Velocity (V0) or regular Velocity (V)? My friend

and I were debating over this all class and we couln't reach an agreement.

2)A car and motorcycle start from rest at the same time on a straight track, but the motorcycle is 25.0m behind the car. The car accelerates at a uniform rate of 3.70m/s2 (meters per second squared), and the motorcycle at a uniform rate of 4.40m/s2. (A) How much time elapses before the motorcycle overtakes the car? (B) How far will each vehicle have traveled by that time? (C) How far ahead of the car will the motorcycle be 2.00seconds later?

-Could someone lead me through these sample problems step by step? I know that you guys aren't here to do my homework, but I don't know where to begin. I'd like to eventually be able to do my homework without having to ask people for help all the time.

Thank you very much!

-Nick
