Question1
The pulley of an ideal Atwood's machine is given an upward acceleration a. Find out an acceleration of each mass and the tension in the string that connects them. Take the accelerations to be positive if they are pointing up. The speeds of the two blocks are not equal in this situation. (Use the following as required: a, m1, m2, and g for the acceleration due to gravity.)
Question2
The momentum of a system that consists of two massive particles is zero. If one of particles has mass 3.0 kg and is moving along the x-axis with velocity -0.5 m/s (such as it is moving to the left with speed 0.5 m/s), what is momentum of the other particle?
