A tee box is 128 feet above its fairway. When a golf ball is hit from the tee box with an initial vertical
velocity of 32 ft/s, the quadratic equation 0 = -16t2 + 32 + 128 gives the time t in seconds when a golf
ball is at height o feet on the fairway.
Part 1
Solve the quadratic equation by factoring to see how long the ball is in the air.
The ball is in the air a total of 4
seconds.
Part 2 out of 3
What is the height of the ball at 1 second?
One second after being hit from the tee, the ball is
feet above the fairway.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you.the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case.part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
