A proton moves through a magnetic field at 21.5% of the speed of light. At a location where the field has a magnitude of 0.00627 T and the proton's velocity makes an angle of 147∘ with the field, what is the magnitude FB of the magnetic force acting on the proton? Use c=2.998×108 m/s for the speed of light and e=1.602×10−19 C as the elementary charge.

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?
