You are working in a washing machine factory. your supervisor has asked you to design a vibration sensor for use on a washing machine when it is in its spin cycle, with the drum turning at 770 rpm. the vibration sensor consists of a cube of aluminum, with 1.50 cm edges, mounted at the top of a steel strip while the bottom of the strip is mounted to the frame of the washing machine. the strip's mass is small compared with that of the cube, but its length is large compared with the dimensions of the cube. you wish the sensor to have a resonance frequency that matches that of the washer in its spin cycle. to determine whether this will be the case, you evaluate the spring constant of the sensor by measuring the force required to pull the cube to the side by a distance of 2.65 cm while the washer is not operating. what is the magnitude of the force needed (in n) if the sensor's resonance frequency matches the spin cycle of the washer? (use 2,700 kg/m3 for the density of aluminum.) n

You are driving directly behind a pickup truck, going at the same speed as the truck. a crate falls from the bed of the truck to the road. (a) will your car hit the crate before the crate hits the road if you neither brake nor swerve? (b) during the fall, is the horizontal speed of the crate more than, less than, or the same as that of the truck?

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
