Use the formula a = |q|*v*B / m, where q is the charge, v is the velocity, B is the magnetic field, and m is the mass. This is alos equal to a = F / m.Since the velocity is not given, use the formula v = (2*KE / m)^(1/2).eport Abuse.

Velocity is a vector quantity that shows the change in distance, time and direction. Depending upon your physics problem, you may know several variables and need to calculate final velocity or average velocity. Choose 1 of the formulas below to calculate velocity.. Plug displacement and time into the equation. Solve the equation. 1  For example, Velocity=50m west/4 hours. 2  In this problem, the average velocity of the biker is 12.5 mph (20.1 km/h) to the west. 3  If you know the initial velocity and the final velocity, you can calculate average velocity in another manner.
