After a short interval of speeding up from rest, the ride spins at a constant rate about its central axis. Passengers may choose to sit in either an inner seat, located a distance R from the axis, or an outer seat, at a distance 1.7R from the axis. The seats are held in place by very strong, rigid metal bars. Bernice is a bit nervous about going on this ride, because she tends to get motion sickness. However, she agrees to go with Gertrude as long as she can choose a seat with the smallest possible magnitude of acceleration, which should give the most comfortable ride. They are having a discussion about whether the inner seats or the outer seats will be better for this purpose. Bernice: "The radial acceleration is equal to v2/r, so it’s inversely proportional to r. The outer seat is at a larger radius, so it should have less acceleration."Gertrude: "But the radial acceleration is also equal to ω2r, which is directly proportional to r. That would mean the inner seat, at a smaller radius, should have less acceleration."a) Whose argument is correct? Which seat actually has less radial acceleration? What is wrong with the argument that is incorrect? Explain your reasoning.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j. b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
