Question

From the window of a building, a ball is tossed from a height y₀ above the ground with an initial velocity of 9.50 m/s and angle of 15.0° 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 the coordinates, with upward the positive y-direction, what are the initial coordinates of the ball? (Use the following as necessary: y₀. Assume SI units. Do not substitute numerical values; use variables only.)

x_i

=____

y_i

=_____

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

v_{i, x}	=____	m/s
v_{i, y}	=____	m/s

c) Find the equations for the x- and y-components of the position as functions of time. (Use the following as necessary: y₀ and t. Assume SI units.)

x	=______	m
y	=_______	m

(d) How far horizontally from the base of the building does the ball 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 below the level of launching?
______s
