You are required to answer the following questions: A.3, B.4, B.6, C.3, D.2, E.2. Submit your problem sets on August 19, 2009 (Wednesday), 13:45 pm. Late submissions will not be accepted no matter what the reason is. A. Momentum 1. A 3.00kg particle has a velocity of (3.00î  4.00ĵ) m/s. (a) Find its x and y components of momentum. (b) Find the magnitude and direction of its momentum 2. A 40.0kg child standing on a frozen pond throws a 0.500kg stone to the east with a speed of 5.00 m/s. Neglecting friction between child and ice, find the recoil velocity of the child. 3. Two blocks of masses M and 3M are placed on a horizontal, frictionless surface. A light spring is attached to one of them, and the blocks are pushed together with the spring between them (Refer to the Figure). A cord initially holding the blocks together is burned; after this, the block of...
