3. Two blocks of masses ma = 2.90 kg and ms = 6.30 kg are connected by a light string that passes over a frictionless pulley. The block ma resting on a frictionless horizontal tabletop is attached and forced against a horizontal spring of negligible mass with one end fastened on the wall (Figure 3.11) and with force constant of 370 N/m. When the spring is compressed to 15 cm, the system is suddenly released. Using the principle of energy conservation, (a) what is the speed of the block ma when the spring reaches equilibrium? (b) As block mg continues to descend, the spring is also stretched to the right by mạ. What is the maximum distance the spring will be stretched? mg

A horizontal spring attached to a wall has a force constant of 850 N/m. A block of mass 1.00 kg is attached to the spring and oscillates freely on a horizontal, frictionless surface as in Figure 5.22. The initial goal of this problem is to find the velocity at the equilibrium point after the block is released. (a) What objects constitute the system, and through what forces do they interact? (b) What are the two points of interest? (c) Find the energy stored in the spring when the mass is stretched 6.00 cm from equilibrium and again when the mass passes through equilibrium after being released from rest. (d) Write the conservation of energy equation for this situation and solve it for the speed of the mass as it passes equilibrium. Substitute to obtain a numerical value. (e) What is the speed at the halfway point? Why isnt it half the speed at equilibrium?
. A mass of 0.75 kg is attached to a relaxed spring with k = 2.5 N/m. The mass rests on a horizontal, frictionless surface. If the mass is displaced by 0.33 m, what is the magnitude of the force exerted on the mass by spring? If the mass is then released to execute simple harmonic along the surface, with what frequency will it oscillate?
A block of mass M rests on a table. It is fastened to the lower end of a light, vertical spring. The upper end of the spring is fastened to a block of mass m. The upper block is pushed down by an additional force 3mg, so the spring compression is 4mg/k. In this configuration, the upper block is released from rest. The spring lifts the lower block off the table. In terms of m, what is the greatest possible value for m?

A scene in a movie has a stuntman falling through a floor onto a bed in the room below. The plan is to have the actor fall on his back, but a researcher has been hired to investigate the safety of this stunt. When the researcher examines the mattress, she sees that it effectively has a spring constant of 77144N/mfor the area likely to be impacted by the stuntman, but it cannot depress more than 13.33cmwithout injuring him.To approach this problem, consider a simplified version of the situation. A mass falls through a height of 3.92mbefore landing on a spring of force constant 77144N/m. Calculate the maximum mass that can fall on the mattress without exceeding the maximum compression distance.
