A car strikes a rigid post at the centre of its bumper. The car is moving at a speed of v-0.63 m/s and has a mass of m- 1350 kg. The bumper can be considered as a simply supported beam on two spring supports connected to the rigid frame of the car. The bumper is made of a polymer with young's modulus E - 2.5 GPa. The cross-section of the bumper is shown in the figure to the right, with the relevant dimensions (not to scale): h-290 mm d=160 mm t-3.9 mm The spring constant of each spring is k 1.3 MN/m. The spring supports are located 21-1.4 m from each other, (and 1-0.7 m from the point of impact).

An inclined plane of angle e = 20.0° has a spring of force constant k = 510 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in the figure below. A block of mass m = 2.61 kg is placed on the plane at a distance d = 0.297 m from the spring. From this position, the block is projected downward toward the spring with speed v = 0.750 m/s. By what distance is the spring compressed when the block momentarily comes to rest?

h L/2 L/4 MR Ms A horizontal rod of length L and mass MR = 2.6 kg is used to hang a sign on a wall. The right end of the rod is attached to the wall by a hinge. A wire having tension T runs from the center of the rod to a place on the wall a distance h above the hinge as shown. The wire makes an angle 0 = 25° with the rod. The sign has mass Ms = 0.867 kg and hangs distance L/4 from the end of the rod. The system is in equilibrium. What is the tension T in the wire that runs between the wall and the rod? T = 60.35 N %3!
