Students/Parents: Thank you for considering me as you tutor. I have over 7-years of experience providing top-of-the-line service for hundreds of students taking college level mathematics, and physics. I have a Bachelor’s of Science in Mathematics with an emphasis of pure math, and am currently in graduate school for mathematics. I love to explain complex information, and am able to do this in a simple fashion that students respond to very quickly.

Two plane mirrors intersect at right angles. A laser beam strikes the first of them at a point 11.5 from their point of intersection, as shown in the figure For what angle of incidence at the first mirror will this ray strike the midpoint of the second mirror (which is 28.0 long) after reflecting from the first mirror?

Physics Problem on the Acceleration Vector

FREE
(1)
A jet plane is flying at a constant altitude. At time t1 = 0 it has components of velocity vx = 90 m/s, vy = 110 m/s. At time t2 = 30.0 s the components are vx = -170 m/s, vy = 40 m/s. (a) Sketch the velocity vectors at t1 and t2. How do these two vec- tors differ? For this time interval calculate (b) the components of the average acceleration, and © the magnitude and direction of the average acceleration.
