A car with a mass of 980 kg is initially traveling east toward an intersection with a speed of v - 21.6 m/s and a 1500 kg pickup is traveling north toward the same intersection. The car and truck collide at the intersection and stick together. After the collision, the wreckage (car and truck) moves off in a direction of 42.0 above the x-axis. Determine the initial speed of the truck and the final speed of the wreckage in meters per second. initial speed of the truck m/s final speed of the wreckage m/s\fMY NOTES A thin block of soft wood with a mass of 0.076 kg rests on a horizontal frictionless surface. A bullet with a mass of 4.67 g is fired with a speed of 593 m/s at a block of wood and passes completely through it. The speed of the block is 22 m/s immediately after the bullet exits the block. (a) Determine the speed (in m/s) of the bullet as it exits the block. X Knowing that momentum is conserved, see if you can write a statement of conservation of momentum that will allow you to determine the final speed of the bullet. m/s (b) Determine if the final kinetic energy of this system (block and bullet) is equal to, less than, or greater than the initial kinetic energy. O equal to the initial kinetic energy O less than the initial kinetic energy greater than the initial kinetic energy (c) Verify your answer to part (b) by calculating the initial and final kinetic energies of the system in joules.
