for B4, break the initial velocity into its horizontal and vertical components.
v (horizontal)=vcostheta
v (vertical)= vsintheta
sub them into their respective equations of motion (d= vt for horizontal) and d= voT + 1/2aT^2 for vertical. isolate the t variable from the horizontal equation, sub it into the vertical equation, and solve for V.
should be 5.03 m/s.


a good friend of mine is gonna go to Uni for physics, i've always thought he was crazy
