Unformatted text preview: Final Exam 5 problems, 20 points each 1. (20 points) A canon on a horizontal surface fires a cannonball with initial speed v at an angle θ above the horizontal. There is a wind that gives rise to a constant horizontal force opposing the cannonball’s motion. The cannonball is observed to be falling straight down when it lands. Find the horizontal position of the cannonball when it lands in terms of v , θ , and g . Neglect the initial height of the cannonball. 2. (20 points) Two blocks with masses m 1 and m 2 are on an inclined plane that makes an angle θ with the horizontal. Block 1 has a spring bumper with spring constant k . There is a coefficient of static friction μ 1 between block 1 and the plane that prevents it from sliding. Block 2 is released from rest a distance d from block 1, and slides down and collides with block 1. What is the minimum value of μ 1 such that the collision does not cause block 1 to move?...
