A thin stick of length 80.0 cm and mass 120.0 g has two small spherical masses attached

to its opposite ends (treat them as point masses). One mass is 20.0 g and the other mass is

50.0 g. The stick rotates frictionlessly about a horizontal axis passing through its centre. If the

stick starts from rest in a horizontal position, what is the linear speed of the larger spherical

mass at the moment that it is passing through its lowest point?

please include any free body diagram if required

Two small metal cubes with masses 2.0 g and4.0 g are tied together by a 4.9-cm-long massless string and are at rest on a frictionless surface. Each is charged to +2.2 μC . The string is cut. What is the speed of each sphere when they are far apart? Hint: There are two conserved quantities. Make use of both. The mechanical energy of the system is 0.89 J and the tension in the string is 18.1 N
