- A A wooden plank is placed on top of two identical, solid, parallel cylindrical rollers, as shown in the figure below. The plank has a mass of M= 5.40 kg, and the rollers each have a mass of m= 2.00 kg and a radius of R = 6.00 cm. The plank is pulled by a constant horizontal force F of magnitude 7.20 N applied to the end of the plank and perpendicular to the axes of the cylindrical rollers. The cylinders roll without slipping on a flat surface, and there is also no slipping between the cylinders and the plank. At the instant shown in the figure, the rollers are equidistant from the ends of the plank. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) (a) What is the magnitude (in m/s2) and direction of acceleration of the plank at the instant shown? m/s² magnitude direction --Select--- (b) What is the magnitude (in m/s2) and direction of acceleration of the centers of mass of the rollers at this…A lamina occupies the part of the disk x² + y < 16 in the first quadrant and the density at each point is given by the function p(x, y) = 4(x2 + y²). %3D A.

(Give your answer in N m.) c. How far can Lancelot ride out along the bridge before the cable breaks? (Give your answer in m.) Note: At his maximum distance, the torque from the cable will equal the torque from both the weight of the bridge and the weight of Lancelot.You have a summer internship at NASA and are working on plans for a new space station to be launched into orbit around the Earth. The design of the space station is shown. i It is to be constructed in the shape of a hollow ring of mass 52,000 kg. The structures other than the ring shown in the figure have negligible mass compared to the ring. Members of the crew will walk on a deck formed by the inner surface of the outer cylindrical wall of the ring, with radius r = 140 m. The thickness of the ring is very small compared to the radius, so we can model the ring as a hoop. At rest when constructed, the ring is to be set rotating about its axis so that the people standing inside on this deck experience an effective free-fall acceleration equal to g. The rotation is achieved by firing two small rockets attached tangentially to opposite points on the rim of the ring. Your supervisor asks you to determine the following: (a) the time interval during which the rockets must be fired if each…
