The ball lands on the spring, and the spring compresses a maximum distance of d= 0.2 m before the ball momentarily comes to a stop. If the spring constant is 882 N/m, how much work does the spring do to the ball during this process?...

A 0.02 kg bullet is shot into an 3.0 kg block of wood suspended from a 0.5 m long string. The bullet becomes imbedded in the block of wood, and the block (with the bullet inside) swings up, as shown in the figure. If the speed of the bullet just before impact is 300 m/s, how high vertically does the block...

A 75 kg person stands motionless on roller skates and then fires a gun horizontally. The bullet has mass of 0.10 kg and a speed as it leaves the barrel of the gun of 200 m/s. Assuming that friction and air resistance can be neglected, what is the person's speed after firing the gun? 18. A 3.75 m/s 0.267 m/s В 12.0...

Tim attaches the string of a 0.10 kg yo-yo to his finger and releases the yo-yo from rest. As the yo-yo spins down, Tim keeps his finger motionless, which allows the yo-yo to be treated the same as a freely rolling object. After the yo-yo drops a distance of 0.90 m, it has a translational speed of 4.0 m/s and an...
