The figure shows a top view of a 50 kg horizontal uniform disk with a radius of 2 m that can rotate about a vertical axis through its center. The disk is initially at rest. A 20 kg point mass is moving at a speed of 30 m/s along a path that is tangent to the rim of the disk. At a certain moment, the point mass contacts the rim at point P and becomes attached to the disk. Determine the linear (tangential) speed of the point mass immediately after it becomes attached. Express your answer in m/s.

A kg particle oscillates horizontally at the end of an ideal spring. The displacement-time graph of its motion is shown in the figure. A = m and t3= s. When the particle is located at 50% of the amplitude from the equilibrium position, determine its kinetic energy (K) in joules.

An enclosed container is filled with an unknown gas, an unknown liquid, and water. h1= m and h2 = m. Given that the density of the unknown liquid is 780 kg/m³, the density of water is 1000 kg/m³, and the pressure of the gas is Pgas = × 104 Pa, determine the pressure at the bottom of the container in Pa.
