1. A ball with a mass of 200g, tied with a thread, rotates in a horizontal plane. The spin period is 2 s. How strong is the ball on the spinning thread? The length of the thread is 0.5 m 2. What is the maximum speed at which a cyclist can move on a bend and at an angle from the vertical, he should deviate to the side of the bend, so as not to fall, if the coefficient of friction of the wheel from the road is 0.4 and the radius of curvature of the road is 100m
