Answer #1

Use momentum conservation principle to find the speed of recoil for the rifle. Use the speed of the rifle and the bullet to find the required kinetic energy releasedг Eьст) = — л (ms) 1 + (- 939) (@от X55-t) t = эя slm TS T on (s[мм 939)(-от Хss-t) + л (+o-3) = 0 momentum conservation, con

    Forensic scientists can determine the speed at which a rifle fires a bullet by shooting into a heavy block hanging by a wire. As the bullet embeds itself in the block, the block and embedded bullet swing up; the impact speed is determined from the maximum angle of the swing (a) Which would make the block swing higher, a 0.204 Ruger bullet of mass 2.14 g and muzzle speed 1290 m/s or a 7-mm Remington Magnum bullet of mass 9.71...

    Agent Arlene devised the following method of measuring the muzzle velocity of a rifle. She fires a bullet into a 4.200-kg wooden block resting on a smooth surface, and attached to a spring of spring constant k = 145.0 N/m . The bullet, whose mass is 7.750 g , remains embedded in the wooden block. She measures the maximum distance that the block compresses the spring to be 9.460 cm. Part A What is the speed v of the bullet?...
