(10%) Problem 10: Modem roller coasters have vertical loops like the one shown in the figure. The radius of curvature is smaller at the top than on the sides so that the downward centripetal acceleration at the top will be greater than the acceleration due to gravity, keeping the passengers pressed firmly into their seats. Otheexpertta.com * 33% Part (a) What is the speed of the roller coaster in m/s at the top of the loop if the radius of...

Part b
(10%) Problem 2: You have a horizontal grindstone (a disk) that is 93 kg, has a 0.36 m radius, is turning at 95 rpm (in the positive direction), and you press a steel axe against the edge with a force of 25 N in the radial direction. Otheexpertta.com ? 50% Part (a) Assuming that the kinetic coefficient of friction between steel and stone is 020 calculate the angular acceleration of the one in rad/s2 at 50% Part (b)...

answer each problem please and show work
(20%) Problem 5: You have been hired to design a family-friendly see-saw. Your design will feature a uniform board (mass M-6 kg, length L -2.7 m) that can be moved so that the pivot is a distance d from the center of the board. This will allow riders to achieve static equilibrium even if they are of different mass, as most people are. You have decided that each rider will be positioned so...

please answer all parts a,b,c,d
(17%) Problem 2: A wire, bent into a rectangle with sides a = 0.075 m and b = 0,045 m, is in a magnetic field B directed perpendicularly to the face of the wire, as shown. The perpendicular component is a function of time as B(t) = Asinot), where A = 0.45 T. 6 = 9 rad/s. In this problem, take the normal vector to the surface of the loop to be parallel to the...
