Hey everyone, trying to figure out how to do two of these physics problems and was hoping I could get some quick help from you pros.

Here's the first one:

One swimmer in a relay race has a .50 s lead and is swimming at a constant speed of 4.00 m/s. The swimmer has 50m to swim before reaching the end of the pool. A second swimmer moves in the same direction as the leader. What constant speed must the second swimmer have in order to catch up to the leader at the end of the pool?

Ok so let's see. I was trying to think if I could go about this algebraically. Maybe create two linear functions and find out where they intersect? Probably not though, I'm sure I could do this if I was trying to find when they'd meet if I had the second swimmer's velocity. So any help on how to solve this one would be great.

Second one:

A ball is thrown vertically upward with a speed of 25 m/s from a height of 2m.

a. How long does it take to reach its highest point?
b. How long does the ball take to hit the ground after it reaches its highest point?

These are the only two problems I'm kind of stuck on. Mind you, this is my first year of physics and first year out of a shitty math program that destroyed any type of math ability I had before I was forced to take it. Thanks guys

2. See, programming is for people who love computers and hate people. I never spend enough time on any games to beat them because I'd rather be outside doign stuff with my friends...

...who sadly would rather play MMORPGs or Paper Mario 2 all day than even acknowledge my presence.

Poor Dan, losing his freinds to MMORPGs and fat plumbers.

I didn't write the book

But I see the point you're trying to make

If you want to call me awesome, don't sugar coat it
