A 4.41-g bullet is moving horizontally with a velocity of +354 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks are moving after the collision with the bullet. The mass of the first block is 1199 g, and its velocity is +0.644 m/s after the bullet passes through it. The mass of the second block is 1576 g . (a) What is the velocity of the second block after the bullet imbeds itself? (b) Find the ratio of the total kinetic energy after the collision to that before the collision. (a) Before collision (b) After collision (a) vblock2 = Number Units (b) KEafter/KEbefore = Number Units

Integrated Concepts - Simple Harmonic Motion, Collision (stick together) As in Figure (a), a 3.91 kg block is attached to a spring with a force constant of 700.00 N/m. The green vertical dashed line indicates the equilibrium position (x = 0). A bullet of 0.075 kg moves toward the block at a speed of v0 = 470.00 m/s. The bullet is embedded in the block after the collision as in figure (b). (i) Find the common speed v of the Block + Bullet after the collision. Hint: What physics law is used for collisions? m/s (ii) The Block+Bullet moves on a frictionless horizontal surface and compresses the spring. What is the x in Figure (c) when the Block+Bullet reaches a momentary rest? Report x as NEGATIVE. m (iii) How much time does it take the Block+Bullet to move from figure (b) to figure (c)? (iv) What is the speed of the Block+Bullet when it reaches x2 = −0.46 m? m/sIntegrated Concepts - Simple Harmonic Motion, Collision (stick together) As in Figure (a), a 3.91 kg block is attached to a spring with a force constant of 700.00 N/m.

As shown below, a 5.4 g bullet is moving horizontally at 967 m/s when it embeds itself in a 0.704 kg block that is attached to a 510 N/m spring. The block is on a frictionless surface and prior to being struck it was in static equilibrium. As a result of the collision, the system starts exhibiting SHM. Determine the following quantities ω = f = T = vmax = amax = A = amount of TE generated during collision =
