A25 kg block is resting the coefficient of friction between the block and the disk is u-0.3. the disk rotates with a uniform angular velocity. what is most nearly the maximum angular velocity of the disk that will cause the block to slip? 5. on a horizontal circular disk (e. g. turntable) at a radius of 0.2 m from the center.

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
