Physics

From the window of a building, a ball is tossed from a height y0above the ground with an initial velocity of 7.90 m/s and angle of19.0° below the horizontal. It strikes the ground 6.00 s later.

(a) If the base of the building is taken to be the origin of thecoordinates, with upward the positive y-direction, what are theinitial coordinates of the ball? (Use the following as necessary:y0. Assume SI units. Do not substitute numerical values; usevariables only.)

xi =

yi =

(b) With the positive x-direction chosen to be out the window,find the x- and y-components of the initial velocity.

vi, x = _______ m/s

vi, y = _______m/s

(c) Find the equations for the x- and y-components of theposition as functions of time. (Use the following as necessary: y0and t. Assume SI units.)

x =_____ m

y = ____m

(d) How far horizontally from the base of the building does theball strike the ground?

_______m

(e) Find the height from which the ball was thrown.

______m

(f) How long does it take the ball to reach a point 10.0 m belowthe level of launching?
