Hey can you guys give me some help with this physics problem.. having real issues figuring it out, and ive looked all over the internet. Google'd like 100 times...(adsbygoogle = window.adsbygoogle || []).push({});

A Particle at Constant Speed A particle P travels with constant speed on a circle of radius r = 3.35 m (Figure 5-39) and completes one revolution in 20.0 s. The particle passes through O at time t = 0. State the following vectors in magnitude-angle notation (angle relative to the positive direction of x).

The picture of it...

1.) With respect to O, find the particle's position vector at the time t = 5.00 s.

answer: _________ ANGLE: 45degrees

I figured out the angle, but i cant figure out how to get the position vector. Just so u know, in case u try the problem, ive already tried the following answers, that are apparently wrong : 1.05, 4.21, .948, 5.26, and 3.35

the rest of the questions are similar to #1, so if u guys can help me with that one, i can figure out the rest.

Thanks
