At the local swimming hole, a favorite trick is to run horizontally off a cliff that is 5.82 m above the water. One diver runs off the edge of he cliff, tucks into a "ball," and rotates on the way down with an average angular speed of 1.83 rev/s. Ignore air resistance and etermine the number of revolutions she makes while on the way down. Number 1.99 Units rev

A particle moves 6.7 m along a circle of radius 2.0 m. (Enter the magnitudes.) (a) Through what angle does it rotate (in rad)?  rad (b) If the particle makes this trip in 1.0 s at a constant speed, what is its angular velocity (in rad/s)?  rad/s (c) What is its acceleration (in m/s2)?  m/s2

The propeller of a World War II fighter plane is 2.50 m in diameter. (a) What is its angular velocity in radians per second if it spins at 1100 rev / min? Enter to 3 significant figures W (b) What is the linear speed of its tip at this angular velocity if the plane is stationary on the tarmac? Enter to 3 significant figures V= rad/s (c) What is the centripetal acceleration of the propeller tip under these conditions? Calculate it in meters per second squared Enter to 3 significant figures ac g m/s ac = ✔m/s² Compare the centripetal acceleration to the acceleration due to gravity g. Is the centripetal acceleration very large or very small compared to g? Enter to 3 significant figures = ✓ (d) State what force provided this centripetal acceleration.

A wheel rotates about a fixed axis with an initial angular velocity of 20 rad/s. During a 5.0 second interval, the angular velocity decreases to 10 rad/s. Assume the angular acceleration is constant during the 5.0 second interval.  How many radians does the wheel turn through during the 5.0 s inteval?
