For Que. 1b, I suggest you draw Free-Body Diagram for the system by taking kinetic friction in the upward direction and then apply Newton's Laws of Motion as you might have done for solving Que. 1a. It's just the matter of directions and algebra and you'll get the answer. << Mentor Note -- post...

I am sorry, I didn't know. Just joined the Forum now, will keep that in mind.

TIme of Flight= 2v0sinθ/g and Horizontal Range=v02sin2θ/g Looking at both the equations, it's easily concluded that by increasing v0 both Time of Flight and Horizontal Range will increase. Not the tricky part is with θ. For the given value of v0, Horizontal Range at θ and 90°-θ are equal...
