A wheel on a game show is given an initial angular speed of 1.22 rad>s. It comes to rest after rotating through 0.75 of a turn. (a) Find the average torque exerted on the wheel given that it is a disk of radius 0.71 m and mass 6.4 kg. (b) If the mass of the wheel is doubled and its radius is halved, will the angle through which it rotates before coming to rest increase, decrease, or stay the same?...

A particle has an initial speed of 27 m/s rightward from the origin at t-0. It decelerates at 6t m/s2 (t in seconds). Find the speed after it has traversed 10m of distance. At what time does this occur 1. 2. At t = 0 a particle has a speed of 8 m/s rightward and is located at s-10m. Knowing a 2v3 (v in m/s) find the location and velocity at 4 seconds. What is...

An early method of measuring the speed of light makes use of a rotating slotted wheel. A beam of light passes through a slot at the outside edge of the wheel as in the figure, travels to a distant mirror, and returns to the wheel just in time to pass through the next slot in the wheel One such slotted wheel has a radius of 6.3 cm and 110 slots at its edge. Measurements...
