PH131 Written HW #7 Fall 2015 In Figure below, a ball of mass m is connected by means of two massless strings, each of length L, to a vertical, rotating rod. The strings are tied to the rod with separation d=L, and are taut. A) Draw and label all the forces on mass m.

Mid size law firm partner salaryThe string passes over a frictionless, massless pulley. The inclines are frictionless, but the horizontal surface has coefficient of kinetic friction 0.45. Block A has mass 5kg. The system accelerates at 4 m/s2. Find the mass of Block B. Here is the force diagram for this problem. The blocks will move together, so we can consider the motion of

Connected Objects If there is a pulley, it is easiest to have the coordinate system follow the string: Lecture 12 22/29 Example: Connected Blocks Block of mass m 1 slides on frictionless tabletop. It is connected by a string and pulley to a hanging mass m 2. Find the acceleration a and string tension T. Lecture 12 23/29 ∑F1, 1 1x == ⇒ =Tma T ma
