Q. In a giant accelerator protons are accelerated to very high speeds and then collided with a fixed target. The 3.8 T magnetic field in the giant ring exerts a magnetic force of 1.035×10-10 N on the proton. How fast is the proton travelling?
Q. At t = 0, a particle leaves the origin with a velocity of 9 m/s in the positive y direction and moves in the xy plane with a constant acceleration of (-2 i -4 j) m/s2. At t = 1 s, what is the velocity of the particle in the x direction?
