(b) A projectile is fired up an incline (incline angle $) with an initial speed v, at an angle 0; with respect to the horizontal (0; > $) as shown in Figure. (a) Show that the projectile travels a distance d up the incline, where Path of the projectile d 2v,? cos0, sin(0; – 4) d = g cos? 6 (b) For what value of 0; is d a maximum, and what is that maximum value?
