$45$ In Fig. $4-40,$ a ball is launched with a velocity of magnitude

$10\mathrm{.}0\frac{m}{s},$ at an angle of $50\mathrm{.}0$ to the horizontal. The launch point is at

the base of a ramp of horizon$-$

tal length $d_1=6\mathrm{.}00m$ and

height $d_2=3\mathrm{.}60m.$ A plateau

is located at the top of the

ramp. $($a$)$ Does the ball land on

the ramp or the plateau? When

it lands, what are the $($b$)$ mag$-$

nitude and $($c$)$ angle of its dis$-$
