There is a magnetic field pointing upward (say along the y-axis) and a particle going 32-degrees above the x-axis (or 58-degrees to the magnetic field)
The problem asks if the speed of the particle is increasing, decreasing or constant. It also asks if the x, y, and z components for speed are increasing, decreasing, or constant.
The Attempt at a Solution
I figured that the direction of the field is coming out of the page, but don't know what is happening to the different speeds. I'm guessing the x/y components and overall speed stay the same but the z speed increases because there is a force acting on it.
