Unformatted text preview: Patel (pnp223) – homework 07 – Turner – (92160) 1 This print-out should have 11 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 4) 10.0 points Consider the setup of a gun aimed at a target (such as a monkey) as shown in the figure below. The target is to be dropped from the point A at t = 0, the same moment as the gun is fired. The bullet hits the target at a point P . Let the initial speed of the bullet be v = 107 m / s, let the angle between the vector vector v and the horizontal ( x-) direction be θ = 53 . 6 ◦ and let AB = 92 . 1 m. The distance d = OB is the x-coordinate of the target. Denote the time taken to hit the target by t . v θ ℓ h x y O A B P The acceleration of gravity is 9 . 8 m / s 2 . This time is given by 1. t = d v cot θ . 2. t = d v cos θ . 3. t = d v tan θ . 4. t = d v sin θ ....
