In a popular amusement park ride, a rotating cylinder of radius3.00 m is set in rotation at anangular speed of 6.00 rad/s, as inFigure P7.51. The floor then drops away, leaving the riders suspended against the wall in a vertical position. What minimum coefficient of friction between a rider's clothing and the wall isneeded to keep the rider from slipping? (Hint: Recall that the magnitude of the maximum force of static friction is equal toµn, where n is the normal force - in this case, the force causing the centripetal acceleration.)
A circular loop lieswith its plane normal to a magnetic field given by B=(2.500- 0.0400t) T, Calculate the radius of the loop
If a system in equilibrium with two masses m1 and m2 are placed at distances d1 and d2 from the fulcrum, then f1 d1= f2 d2. Is this the same as saying that m1 d1= m2 d2? Give details.
A proton travels with a velocity of v = (1.5 x 10^5)m/s i + (4.0 x 10^5)m/s j ? and then enters a magnetic field B = (1.5T)i? . Describe the motion the proton will experience
