An electron follows a helical path in a uniform magnetic field given by:B =(20i^β50j^β30k^)mTAt time t = 0, the electron's velocity is given by:βv=(40i^β30j^+50k^)m/sa. What is the angle Ο between v and B. The electron's velocity changes with time. Do b. its speed c. the angled. What is the radius of the helical path?

Emmy kicks a soccer ball up at an angle of 45Β° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive β and βdirections, respectively, and use β10 m/s2 for the downward acceleration due to gravity.
