A ball is tossed from an upper$-$story window of a building. The ball is given an initial velocity of $9\mathrm{.}50$ m$/$s at an angle of $15\mathrm{.}0$ below the horizontal. It strikes the ground $4\mathrm{.}00$ s later.

$($a$)$ How far horizontally from the base of the building does the ball strike the ground?

m

$($b$)$ Find the height from which the ball was thrown.

m

$($c$)$ How long does it take the ball to reach a point $10\mathrm{.}0$ m below the level of launching?
