Part C. Problems For full marks intermediate steps must be shown. 1) A ball is thrown with a speed of 20 mfs and lands at the same level from which it was launched. The range of the ball is 35.3 m. a) What is the angle between the initial velocity of the ball and the horizontal plane? (3A) b} What is the time of flight? {BA} c) What is the maximum height? [3A] 2) Two hockey pucks of equal mass undergo a headon collision. Initially, one puck is moving with a speed of 5.4 mfs while the other is at rest. After the collision, the velocity of the first puck has the previous direction and equals 0.30 m/s. Find (a) the velocity of the other puck (3A) and {blthe percentage ofthe total kinetic energy lost in the collision {BA}. 3) A block attached to a horizontal spring of force constant 75 N/m oscillates with an amplitude of 0.15 m. Friction is negligible. The speed of the block is 1.7 m/s when the displacement is {1.12 m from the equilibrium position. a) What is the mass of the block? (3T) b} What is the maximum speed of the block? {ST} 4) Three charges, qA:+1.O uC, C|g=+2.0 uC, and qcz-l uC, are placed at the corners A, B, and C of AABC. In the triangle, AC=1 m, 13:30\
