(8%) Problem 7: A quarterback throws a football with an initial velocity v at an angle 0 above the horizontal. Assume the ball leaves the quarterback's hand at ground level and moves without air resistance. All portions of this problem will produce algebraic expressions in terms of v. 0, and g. Let the origin of the Cartesian coordinate system be the ball's initial position. 33% Part (a) Write an expression for the magnitude of the vertical component, vo,y, of the football's initial velocity. = cos(a) cos(Q) cos(0) ( sin(a) sin(o) sin(0) 145 7 8 9 6 HOME B 0 1 2 3 d g h 0 m t V NO CHACE Grade Summary Deductions Potential Submissions 0% 100% Attempts remaining: 1 (83% per attempt) detailed view Hints: 0% deduction per hint.
