A roadway is designed for traffic moving at a speed of 66m/s. A curved section of the roadway is in the shape of a circular arc of 290-m radius. This section of roadway is banked so that a vehicle travelling at 66m/s will experience no net lateral acceleration. What is the angle at which the roadway is banked? 57 degrees 51 degrees 53 degrees 55 degrees 59 degrees​

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.
