I think its 2 seconds into flight.
So the components of x and y are after 2 seconds.
Ux= Vx (Horizontal is always constant)
So
DeltaY = Ux.t+1/2.a.t^2
Find DeltaY:
DeltaY= 39.2 x2 + 1/2x -9.8x 2^2
DeltaY=98
So we Got DeltaY and can find the initial Vertical Velocity (Uy)
Because...
Still dont understand your initial motive in saying you hope everyone is like me in the exam.
95 isnt easy to get, and if it is
EDIT: Which its not
Why do you say you will get 80.

"The mathematical term \|* 1-(v^2/c^2) is fundamental to our understanding of einsteins theory of special relativity." *its a square root sign:rofl:
(a) State qualitatively how the value of this mathemetical term varies as the velocity (v) increases.
(b) outline how thie...
