Q. A 2.00 kg stone attached to a rope 4.00m long is whirled in a circle horizontally on a frictionless surface, completing 5.00 revolutions in 2.00 s. Calculate the magnitude of the tension in the rope.
Q. When a certain spring is stretched by an amount x, it produces a restoring force of F(x) = ax=bx^2, where a and b are constants. How much work is done by an external force in stretching the spring by an amount D from its equilibrium length?
