(b) A projectile is launched with an initial speed of 200 m/s at an angle of 60° with respect to the horizontal direction. Compute the range R as measured up the incline (as shown in Figure 1b), i.e. the distance between the point B at which the projectile hits the inclined plane and the initial launch point A. The inclined plane makes an angle of 20° with respect to the horizontal direction. 200 m/s 60° A 20° R B
