Arubber bullet of mass m is fired from a rifle into a stationary block of 25 m. the bullet remains in the block and both the bullet and the block move off with a common velocity. assume this is an inelastic collision in a closed system. which best describes the final momentum of the bullet/block? the final momentum of the bullet/block is zero. the final momentum of the bullet/block is equal to the initial momentum of the bullet. the final momentum of the bullet/block is less than the initial momentum of the bullet. the final momentum of the bullet/block is more than the initial momentum of the bullet.

A10.0-g bullet is fired into, and embeds itself in, a 1.95-kg block attached to a spring with a force constant of 16.6 n/m and whose mass is negligible. how far is the spring compressed if the bullet has a speed of 300 m/s just before it strikes the block and the block slides on a frictionless surface? note: you must use conservation of momentum in this problem because of the inelastic collision between the bullet and block.

Consider a rifle, which has a mass of 2.44 kg and a bullet which has a mass of 150 grams and is loaded in the firing chamber.when the rifle is fired the bullet leaves the rifle with a muzzle velocity of 440 m/s; a. what will be the momentum of the rifle immediately before the bullet is fired? b. what will be the momentum of the rifle-bullet combination before the bullet is fired? c. what will be the momentum of the bullet immediately after the rifle has been fired? d. what will be the momentum of the rifle immediately after it has been fired? e. what will be the momentum of the rifle-bullet combination immediately after the bullet had been fired? f. what will be the velocity of the rifle immediately after the rifle has been fired? g. after the rifle has been fired it comes into contact with the marksman’s shoulder and then comes to a halt during a timeperiod of 0.38 seconds. what is the average force applied to the rifle by the shoulder? after the bullet leaves the rifle is strikes a block of wood which has a mass of 5.10 kg. and is sitting on a horizontalsurface which has a coefficient of sliding friction ofm= 0.83 .h. what will be the velocity of the bullet-block combination immediately after the bullet strikes the block of wood? i. how far will the block slide along the horizontal surface before it comes to a halt? j. how much energy was lost as the bullet was lodged in the block of wood?
