9 Given: A mechanical system is shown on the right. You may neglect the masses of the pulleys and cords, and you may assume that the block is initially at rest. Find: a) The kinematic (i.e., dependent motion) equations for the motor-pulley system. This includes the equations for B position, velocity, acceleration, and displacement b) The displacement of block A if the motor pulls down the D cord, which connects motor M and pulley...

C What is conserved in the following cases (linear momentum, angular momentum about an axis, mechanical energy, tionle kinetic energy, none of these)? There may be more than one conserved quantity. For this question, you do not have to show your reasoning (a) Two masses are released from rest, from the positions shown in the figure, in a frictionless hemispherical bowl. The masses collide and stick together. Note that the circular motion is characterized simultaneously by the linear and angular...
