I- A particle moves along the x axis. Its position varies with time according to the expression x= - 41 + 2r where x is in meters and t is in seconds. The position-time graph for this motion is shown in Figure. Note that the particle moves in the negative x direction for the first second of motion, is momentarily at rest at the moment t = 1 s, and moves in the positive x direction at times t> 1 s. (A) Determine the displacement of the particle in the time intervals t= 0 to 1=Is and t = 1s to 1 = 3 s. B) Calculate the average velocity during these two-time intervals C) determine the instantancous velocity and instantaneous speed at t= 0.5 s.

A hydraulic press must be used to press-fit two components together in an assembly process. The system must generate at least 975 lb of force to perform the press fit. The piston at the input cylinder is pushed with a force of 250 lb and has an area of 30 in.2. The output can use up to 15 cylinders that are each 30 in.?. How many output cylinders must be incorporated into the design? Hint (you cannot have a fraction of a tangible item - i.e. you cannot have a decimal of a cylinder)
