### Question Description:

A particle travels counterclockwise around the origin at constant speed in a circular path that has a diameter of 2.50 m, going around twice per second. Point Q is on the path halfway between points P and R, which lie on the x axis and the y axis, respectively. State the following velocites as vectors in polar notation. (a) What is the particle’s average velocity over the interval PR? (b) What is its average velocity over the interval PQ? (c) What is its instantaneous velocity at point P?,If there were no air resistance, how fast would you have to throw a football at an initial 45° angle in order to complete an 80 meter pass?,For c) in the problem, you only stated 15.7 m/s due north. Did you use the Pythagorean theorem to come up with that? and what is the degrees for c)?,Ohkay, Thank you so much! (:
