A block of mass m₁ = 10.0 kg is connected to a block of mass m₂ = 34.0 kg by a massless string that passes over a light, frictionless pulley. The 34.0-kg block is connected to a spring that has negligible mass and a force constant of k = 200 N/m as shown in the figure below. The spring is
unstretched when the system is as shown in the figure, and the incline is frictionless. The 10.0-kg block is pulled a distance h = 22.0 cm down the incline of angle 0 = 40.0° and released from rest. Find the speed of each block when the spring is again unstretched.

Truck suspensions often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as in the figure below. The helper spring engages when the main leaf spring is compressed by distance yo, and then helps to
support any additional load. Consider a leaf spring constant of 5.45 × 105 N/m, helper spring constant of 3.60 × 105 N/m, and y = 0.500 m.

Some 1800 years ago Roman soldiers effectively used slings as deadly weapons. The length of these slings averaged about 81 cm and the lead shot that they used weighed about 30 grams. If in the wind up to a release, the shot rotated around the Roman slinger with a period of .15 seconds. Find the maximum acceleration of the shot before being released in m/s^2 and report it to two significant figures.arrow_forwardIn the movie Fast X, a 10100 kg round bomb is set rolling in Rome. The bomb gets up to 17.6 m/s. To try to stop the bomb, the protagonist Dom swings the counterweight of a crane, which has a mass of 354000 kg into the bomb at 3.61 m/s in the opposite direction. Directly after the collision the crane counterweight continues in the same direction it was going at 2.13 m/s. What is the velocity (magnitude and direction) of the bomb right after the collision?arrow_forward
