$-445$ 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 horizontal length $d_1=$

Fig. $4-40$ Problem $45.6\mathrm{.}00$ m 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$)$ magnitude and $($c$)$ angle of its displacement from the launch point?
