Suppose a piece of food is on the edge of a rotating microwave oven plate. does it experience nonzero tangential acceleration, centripetal acceleration, or both when: (a) the plate starts to spin? (b) the plate rotates at constant angular velocity? (c) the plate slows to a halt?

Select the word from the list that best fits the definition classification of most stars on the h-r diagram

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
