Check Your Understanding There is a second solution to the system of equations solved in this example (because the energy equation is quadratic): v1.f=-2.5m/s , v2.f=0 . This solution is unacceptable on physical grounds; what’s with it?
The coefficient of friction between the block of mass ml = 3.00 kg and the surface in Figure P7.22 is k = 0.400. The system starts from rest. What is the speed of the ball of mass, m2 = 5.00 kg when it has fallen a distance h = 1.50 m? Figure P7.22
A 6 000-kg freight car rolls along rails with negligible friction. The car is brought to rest by a combination of two coiled springs as illustrated in Figure P6.27 (page 188). Both springs are described by Hookes law and have spring constants k1 = 1 600 N/m and k2, = 3 400 N/m. After the first spring compresses a distance of 30.0 cm, the second spring acts with the first to increase the force as additional compression occurs as shown in the graph. The car comes to rest 50.0 cm after first contacting the two-spring system. Find the cars initial speed.

Assume that the force of a bow on an arrow behaves like the spring force. In aiming the arrow, an archer pulls the bow back 50 cm and holds it in position with a force of 150 N. If the mass of the arrow is 50 g and the “spring” is massless, what is the speed of the arrow immediately after it leaves the bow?
Two blocks of masses m and 3m are placed on a frictionless, horizontal surface. A light spring is attached to the more massive block, and the blocks are pushed together with the spring between them (Fig. P8.7). A cord initially holding the blocks together is burned; after that happens, the block of mass 3m moves to the right with a speed of 2.00 m/s. (a) What is the velocity of the block of mass m? (b) Find the systems original elastic potential energy, taking m = 0.350 kg. (c) Is the original energy in the spring or in the cord? (d) Explain your answer to part (c).

A block of mass 3.63 Kg slides on a frictionless horizontal tablet at a speed of 1.22 m/s. It comes to rest when it is in its path and compresses a spring whose force constant is 135 N/m. How much the spring is compressed???
A spring clamped to the table shoots Block 1 (110 g, wood) directly into Block 2 (80 g, steel), this perfectlyelastic collision will launch the second block up a ramp. When the spring is compressed 14 cm, the block travels upa ramp that has a height of 86 cm and then compresses another spring (310 N/m) at the top, 5 cm. What then isthe spring constant for the first spring? Assume that all surfaces are frictionless
A mass and spring are arranged on a horizontal, frictionless table as shown in the figure below. The spring constant k = 540 N/m, and the mass is 4.4 kg. The block is pushed against the spring so that the spring is compressed an amount 0.34m, and then it is released. Find the velocity of the mass when it leaves the spring. Answer in m/s
