Abicycle traveled 150 meters west from point a to point b. then it took the same route and came back to point a. it took a total of 2 minutes for the bicycle to return
to point a. what is the average speed and average velocity of the bicycle?
oa.
the average speed is 2.5 meters/second, and the average velocity is
2.5 meters/second east.
ob.
the average speed is o meters/second, and the average velocity is
2.5 meters/second east.
oc.
the average speed and average velocity are both o meters/second.
od.
the average speed is 2.5 meters/second, and the average velocity is
o meters/second.

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply. the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
