A bullet with a mass m₁ = 11.9 g is fired into a block of wood at velocity Ub = 265 m/s. The block is attached to a spring that has a spring constant k of 205 N/m. The block and bullet continue to move, compressing the spring by 35.0 cm before the whole system momentarily comes to a stop. Assuming that the surface on which the block is resting is frictionless, determine the mass my, of the wooden block. mw = kg то ww k www
Two objects of masses m, - 0.42 kg and m, = 0.90 kg are placed on a horizontal frictionless surface and a compressed spring of force constant k = 300 N/m is placed between them as in figure (a). Neglect the mass of the spring. The spring is not attached to either object and is compressed a distance of 9.6 cm. If the objects are released from rest, find the final velocity of each object as shown in figure (b). (Let the positive direction be to the right. Indicate the direction with the sign of your answer.) m/s V2 = m/s a

A 60-N sledge hammer shown in the figure strikes the 90 N wood block which is at rest on the coil spring. The striking velocity of the hammer is óm/sec and the block and hammer are assumed to remain in contact after striking. What is the scale of the spring if the blow causes the spring to be compressed 50mm? Answer in N/mm and in 2 decimals.
1. A riffle bullet with mass 8.00 g strikes and embeds itself in a block of mass 0.992 kg that rests on a frictionless, horizontal surface and is attached to a coil spring (Figure 1). The impact compresses the spring 15.0 cm. Calibration of the spring shows that a force of 0.750 N is required to compress the spring 0.250 cm. (a) Find the magnitude of the block's velocity just after impact. (b) What is the initial speed of the bullet? -150 cm->
A 15.0 kg block is attached to a very light horizontal spring of force constant 475 N/m and is resting on a smooth horizontal table (Figure 1). Suddenly it is struck by a 3.00 kg stone traveling horizontally at 8.00 m/s to the right, whereupon the stone rebounds at 2.00 m/s horizontally to the left. Part A Find the maximum distance that the block will compress the spring after the collision.

A child is bouncing an a trampoline. The child has a mass of 42.5 kg. She leaves the surface of the trampoline with an initial upwards velocity of 10.2 m/s. When she reaches height 1.60 m above the trampoline (still on the way up), she grabs a large (stationary) plastic block. The mass of the block is 6.00 kg. (Figure 1) For this problem, use g = 9.80 meters per second per second for the magnitude of the acceleration due to gravity.
