A 160 lb person is being pulled on a tube in the snow by a four wheeler when the four wheeler starts to spin at 3 rad/s. Initially, the person on the tube is 12 feet from the center of rotation when the towing rope gets wrapped around the axle and begins to pull in at 3 ft/s. Determine the velocity of the person and the tube when they are 4 feet from the center of rotation. Neglect the mass of the four wheeler, tube, and towing rope. Assume the tube is on a smooth surface and that angular momentum is conserved. (108.0 ft/s)

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.
