Physics teacher, Mr. McKee, shoots a .22 caliber rifle at a .30 kg block of wood. The rifle and the wood are mounted on carts that sit on air track, as shown, so that friction is negligible. The 6.0 kg gun fires a 0.020 kg bullet with a speed of 200 m/s. a) what is the final velocity of the block of wood with the bullet lodged inside?

b) what is the recoil velocity of the gun?

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
