The 1.0-meter-long horizontal plank shown below rotates with a constant angular velocity of 10 rad/s in the -y direction, while the smaller member (0.5 m long) rotates about the +z axis with a constant angular velocity of 20 rad/s. a. What's the acceleration of the point p at the instant shown? b. If the point p represents an object with a mass of 0.015 kg, what's the net force acting on the object at the instant shown? X p

Problem 14.47) Disks A, B, C, and D can ślide freely on a frictionless horizontal surface. Disks B, C, and D are connected by light rods and are at rest in the position shown when disk B is struck squarely by disk A which is moving to the right with a velocity vo 12 m/s. The masses of the disks are m,-m,-mc - 7.5 kg, and m 15 kg. Knowing that after impact disks A and B are bound togetherV)...

Please work out 3 clearly and with units. Thanks!
1. A 10-g bullet travels vertically upwards at 1000 m/s, then strikes and passes through a 2.0-kg block initially at rest. The bullet emerges from the block with a speed of 400 m/s because it transfers momentum to the block. (a) How much momentum did the block gain? (b) How fast is the block now moving, and what is its kinetic energy? (c) Using energy considerations only, to what maximum height...
