Question
A quarterback throws a football with an initial velocity v at an angle θ 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, θ, and g. Let the origin of the Cartesian coordinate system be the ball's initial position.
1Write an expression for the magnitude of the vertical component, v0,y0, of the football’s initial velocity.
2).Find an expression for the magnitude of the horizontal component, v0x, of the football’s initial velocity.
3Write an expression for the total time, t-total, the football is in the air.
