One part of this problem has me confused...id appreciate any guidance. I have part (a) and (b) but (c) and (d) are TOTALLY losing me. i don't even know where to begin. THANKS
"An electron's position is given by r=3.00t i - 5.00t^2 j + 3.00 k, with t in seconds and r in meters"
(a) In unit-vector notation, what is the electron's velocity v(t)?
My answer: 3.00 i - 10.0t j+ 0.00 k
(b) What is v in unit-vector notation at t=6.00s?
My answer: 3.00 i - 60.0 j+ 0.00 k
(c) What is the magnitude of v at t = 6.00 s?
(d) What angle does v make with the positive direction of the x-axis at t = 6.00 s?
Thank you.
