3. A projectile is fired up an incline (incline angle º) with an initial speed v, at an angle 0, with respect to the horizontal (0> 0) as shown in ??. (a) Show that the projectile travels a distance d up the incline, where 2 v cos e sin(0- ) d= g cos 0 (b) For what value of 0; is d a maximum, and what is that maximum value? Path of the projectile ya d 16 Figure 2: ASIWO3​
