The force-compression profile of a rubber bumper B is given by FB = Bx, where B = 3.5 x 10° lb/ft and x is the bumper's compression measured in the horizontal direction. Determine the expression for the potential energy of the bumper B. In addition, if the cruiser C weighs 70,000 lb and impacts B with a speed of 5 ft/s, determine the compression required to bringC to a stop. Model C as a particle and neglect C's vertical motion as well as the drag force between the water and the cruiser C. %3D

Answer both questions please!

The three masses in the figure are different. The planes do not have friction with the masses and the plane of mass 3 corresponds to a quarter of a circumference. All three masses are released at the same time. The masses m2 and m3 travel the same distance. The first mass that will reach the bottom of the ramp will be:   m1 m2 m3 m2 and m3 m1 and m2 m1 and m3 they will all arrive at the same time

VA₂ PLANE OF CONTACT ÚB₂ X A B 0 m m velocity = 1.52 On an air hockey table, two pucks of identical mass collide in the middle of the rink. Puck A had an initial and puck B had an initial velocity B = 3.1 according to the x-y axis shown. The plane of contact can be thought of as a line angled 0 = 32° above the x-axis. If the coefficient of restitution is e = 0.41 between the pucks, what are the velocities of the pucks after the impact? s i+ i+ m S m Ⓒ 0 UBC Engineering S
