Slotted arm ob oscillates about the vertical by the action of the rotating crank ca of 5-in length, where the pin a engages the slot. for a constant angular velocity of = 12 rad /sec of the crank ca, determine the angular velocity and acceleration of arm ob for the instant theta = 60o.

moving ball hits still ball. mover stops, hit ball moves. momentum transfer.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
