Apositively charged particle of mass 6.20 10-8 kg is traveling due east with a speed of 75 m/s and enters a 0.47-t uniform magnetic field. the particle moves through one-quarter of a circle in a time of 6.40 10-3 s, at which time it leaves the field heading due south. all during the motion the particle moves perpendicular to the magnetic field.(a) what is the magnitude of the magnetic force on the particle? (b) what is the charge on the particle?

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
