A"barrel of fun" consists of a large vertical cylinder that spins about its axis fast enough so that any person inside will be held against the wall. at an angular speed ω1, an upward frictional force f1 holds a person against the wall without slippingif you double the angular speed (i. e., ω2 = 2 ω1) what is the new friction force f2?

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
