Emmy kicks a soccer ball up at an angle of 45" over a level field. She watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. Assume that air resistance is negligible, and plot the horizon and vertical components of the ball's velocity as a function of time. Consider only the time that the ball is in the air, after being kicked but before landing. Take "north" and "up" as the positive x- and y-directions, respectively, and use g z 10 m/s for the downward acceleration due to gravity.

A ball is thrown into the air at 60° angle to the ground, takes a parabolic path, and is in the air for a total time of 4 s. If the upward direction from the ground is positive, what is the best estimate of the ball’s velocity at a time 3 s after it leaves the ground?
A rugby player passes the ball 9.75 m across the field, where it is caught at the same height as it left his hand. At what angle was the ball thrown if its initial speed was 12.0 m/s, assuming that the smaller of the two possible angles was used? (Answer in Degrees) What other angle gives the same range? (Answer in Degrees) For the pass using the smaller of the two angles, how long is the ball in the air? (answer in Seconds)
A ball is shot from the top of a building with an initial velocity of 18 m/s at an angle θ = 43° above the horizontal. If a nearby building is the same height and 61 m away, how far below the top of the building will the ball strike the nearby building? ( Choose upward as the positive y-direction and express the displacement with the sign of the result, which must be in units of meters and include 1 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take g=9.80 m/s2.)
