A chute delivering shipments of freight is so designed that the boxes starting from rest, receive a uniform acceleration of 18 ft. / sec² on the first section which is 18 ft. long. Then they are retarded by a 6 ft. / sec² uniform deceleration on the next section. It the total time consumed in shooting both sections of 12 sec., determine (1) the time at the first and second sections in sec. (2) the velocity after the time at the first section, in ft. / sec, (3) the distance or displacement of the second section. in ft., and (4) the velocity in ft. / sec. at the end of second section.

Solution 1: Ergonomic Assessment and Improvement. An ergonomic assessment of Paula's workstation could identify areas where adjustments could be made to reduce strain on her wrists. This could include adjusting the height of the workstation, providing wrist supports, or changing the design of the tools she uses. The strength of this solution is that it directly addresses the physical strain causing Paula's discomfort. However, the weakness is that it may require investment in new equipment or tools, and the effectiveness will depend on the specific changes made. Solution 2: Job Rotation. Paula could be rotated between different tasks more frequently, reducing the amount of time she spends on tasks that strain her wrists. This could also include training other workers to perform the welding and gaging operations, allowing for more flexibility in task assignments. The strength of this solution is that it reduces the repetitive strain on Paula's wrists. The weakness is that it requires…
What are crumple zones in cars designed for? O absorbing the shock from bumpy roads changing the direction of the car during impact increasing the time it takes for a car to stop during a crash allowing the car to be scrapped and recycled easily
