Unformatted text preview: Correct answer: 39 . 1008 m. Explanation: Basic Concepts Horizontally, v oh = v cos θ v h = v oh d = v oh t and vertically, v ov = v sin θ v v = v ov-gt h = v ov t-1 2 gt 2 maximum height, so 0 = v ov-gt so that t = v ov g Thus the maximum height is h max = v ov v ov g-1 2 g p v ov g P 2 = 1 2 v 2 ov g Dimensional analysis For h max : m s ÷ m s 2 = m s · s 2 m = s 003 (part 2 oF 2) 10.0 points What horizontal distance will it travel? Correct answer: 207 . 554 m. patel (kp9583) – CW5 – Mackie – (20211) 2 Explanation: The horizontal velocity is constant, and the maximum range is attained in a time of 2 t , so d = v oh · 2 t = v oh 2 v ov g = 2 v oh v ov g Dimensional analysis for d : m s m s ÷ m s 2 = m 2 s 2 · s 2 m = m...
