Hey guys, Im new to the forums. Im currently taking AP Physics in my senior year of high school, and I am having some difficulty solving the following two problems:(adsbygoogle = window.adsbygoogle || []).push({});

1. A ball is shot upward with a velocity of 30ft/s. Another is shot upward a second later at 100ft/s. Where and when do they pass?

2. The equation of motion of a specific particle is x=6t^2+4t^3. X is in feet, t in seconds. Compute the objects initial acceleration and its acceleration when position is 100 feet.

My teacher is infamous for not teaching us how to do most of the stuff, but I was able to figure out the homework minus these two questions. If anyone can help that would be extremely appreciated!

Thanks in advance...
