A jet flying at 137 m/s banks to make a horizontal circularturn. The mass of the jet is2.29 × 105 kg and radius of the turn is 3810 m. find the magnitude of the necessary lifting force.
question a lightning bolt may carry a current of 1.00 x 104 a for a short period of time. what is the resulting
It is common to see birds of prey rising upward on thermals. The paths they take may be spiral-like. You can model the spiral motion as uniform circular motion combined with a constant upward velocity. Assume a bird completes a circle of radius 6...
