What is the force exerted on a moving charge of –2.0 μc at a 20° angle through a magnetic field of 3.0 × 10–4 t with a velocity of 5.0 × 106 m/s? 3.0 × 10–3 n 1.0 × 10–3 n 1.0 × 103 n

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
