STEM Lessons for College Students

3.3 .. CALC A web page designer creates an animation in which a dot on a computer screen has position rS _ 34.0 cm +12.5 cm>s22t24 dn _ 15.0 cm>s2t en. (a) Find the magnitude and direction of the dot’s average velocity between t = 0 and t = 2.0 s.(b) Find the magnitude and direction of the instantaneous velocity at t = 0 t = 1.0 s and t = 2.0 s. (c) Sketch the dot’s trajectory from t = 0 to t = 2.0 s and show the velocities calculated in part (b).

I have not created a lesson for this question yet.

Please leave a comment below with specifics about the question, and I will make a detailed lesson on it as soon as possible. (I can usually have something up within a day.)

NEED IMMEDIATE HELP? Get the student solution manual here: University Physics Manual otherwise, I should be able to get a video lesson up within a day or so.
