A student is swinging a ball on a string overhead in a horizontal plane. The string initially has length ?0 and the ball is moving with an initial speed ?0. The student decides to see how fast they can spin the ball, so they begin moving it faster and faster with a constant tangential acceleration ?? . However, they know that the string is close to breaking, so they decide to keep letting the string get longer and longer in...

An object with weight W is dragged along a horizontal plane by a force acting along a rope attached to the object. If the rape makes an angle with the plane, then the magnitude of the force is F= u sin() + cos(8) where u is a constant called the coefficient of friction. (a) Find the rate of change of F with respect to(0). - W( cos A-sin) (usin 0 + cos 0) df de- (b) When is this...
