Acannon fires a 0.794 kg shell with initial velocity vi = 9 m/s in the direction θ = 42 ◦ above the horizontal. the acceleration of gravity is 9.8 m/s 2 shell’s trajectory curves downward because of gravity, so at the time t = 0.499 s the shell is below the straight line by some vertical distance. your task is to calculate the distance ∆h in the absence of air resistance. first, find what does ∆h depend on (besides g): 1. it depends only on the initial angle θ, and does not depend on the flight time t or the initial velocity vi . 2. it depends on everything: the flight time t, the initial angle θ, and the initial velocity . it depends on the flight time t and the initial angle θ, but does not depend on the initial velocity vi . 4. it is a constant and does not depend on the flight time t or the initial velocity vi or the initial angle θ. 5. it depends only on the initial velocity vi , and does not depend on the flight time t or the initial angle θ. 6. it depends on the flight time t and the initial velocity vi , but does not depend on the initial angle θ. 7. it depends only on the flight time t, and does not depend on the initial velocity vi or the initial angle θ. 8. it depends on some data not given in the problem. 9. it depends on the initial angle θ and the initial velocity vi , but does not depend on the flight time t. question 8, chap 104, sect 6. part 2 of 2 10 points and now calculate the ∆h. answer in units of m.
