At the local swimming hole, a favorite trick is to run horizontally off a cliff that is 6.53 m above the water. One diver runs off the edge of the cliff, tucks into a "ball," and rotates on the way down with an average angular speed of 1.99 rev/s. Ignore air resistance and determine the number of revolutions she makes while on the way down.
A meter stick is allowed to fall from a vertical position and rotate to the ground without slipping. Does the end of the meter stick fall at the acceleration of gravity or less than the acceleration of gravity?
Starting from rest, an airplane propeller begins to rotate with an angular acceleration
a = 0.0600 rad/s2. The propeller radius is 60.0 cm. After exactly 4.00 seconds, calculate the total
linear acceleration of the tip of the propeller. (The total linear acceleration is the vector combination
of the tangential acceleration and the centripetal acceleration.)

Members of the crew walk on a deck formed by the inner surface of the outer cylindrical wall of the ring, with radius r = 100 m. At rest when constructed, the ring is set rotating about its axis so that the people inside experience an effective free-fall acceleration equal to g. (Sec Fig. P11.29.) The rotation is achieved by firing two small rockets attached tangentially to opposite points on the rim of the ring, (a) What angular momentum does the space station acquirer (b) For what time interval must the rockets be fired if each exerts a thrust of 125 N?arrow_forwardWhy is the following situation impossible?
