The position of an electron is given by r= -3.0t î-4.0t2ĵ+ 2.0k (where t is in seconds and the coefficients have the proper units for r to be in meters). (a) (5 points) What is (t) for the electron? (b) (5 points) In unit-vector notation, what is at t = 2.0 s? (c) (5 points) What are the magnitude and direction of is at t = 2.0 s?
