Answer all questions and problems. 2. Each question will be assigned 1 point. 3. Each problem will be assigned 2 points 4. No solution = no points 5. Mobiles and pagers are not allowed during the exam 6. Programmable calculators are not allowed. Good Luck 2 Part I : MC Questions 1. A projectile is thrown with an initial velocity g G ¡ = 3¢̂ + 4£̂ m/s. When it reaches the highest point in its path, the magnitude of its acceleration in m/s 2 is approximately a) 3 b) 4 c) 5 d) 10 2. If you increase the speed of your car by a factor of 3, The kinetic energy will be increased by a factor of a) 3 b) 6 c) 9 d) 10 3. A cylinder is rotating counter-clockwise as shown in the figure. If the angular velocity ω is decreasing uniformly, then the angular acceleration vector ¤ G points in the a) + z direction b) – z direction c) – x direction d) – y direction 4. For the completely inelastic collision shown in the figure, what can be said about the kinetic energy...
