A square plastic chunk with mass 0.750 kg is suspended from the lower end of a light cord that is 1.66 mm long. The plastic chunk is stay still in the beginning without any motion. A bullet with mass 0.0132 kg is on the way to the plastic chunk with a horizontal velocity v0. The bullet hits the plastic chunk and then embedded in it. After collision, combined bullet and plastic chunk swings on the end of the cord. When the plastic chunk has risen a vertical height of 0.800 mm , the tension in the cord is 4.98 N .
What was the initial velocity v0 of the bullet?

**A crate with a mass of 45 kg is suspended from a massless rope that runs vertically upward over a light pulley. The other end of the rope is connected to a 35 kg crate, which lies on a tabletop. The coefficients of the kinetic friction and the static friction between the crate and the surface are 0.3 and 0.5 respectively. An applied force, F, pulls the 35 kg crate to the right. In the first case, the applied force...

A mass m = 1 kg is suspended from a spring that is stretched 1 cm under the influence of the weight of this mass. Now a periodic force is applied external of F (t) = 200 cos (vt) on the mass, which was initially in static balance. Disregarding all friction, get a relationship for position of the mass as a function of time, x (t). Also determine the value of ω which will cause resonance to occur
