For the y I get S(t) = ut + 1/2 a t^2 Y(t) = 4t sin θ -5t^2 therefore I think that u =4 and a=-10 but I'm not sure where the sin theta comes from And for the x I get S(t) = ut + 1/2 a t^2 X(t) = 4t cosθ Therefore I think that u =4 again but I have nothing for a?! And I'm unsure where cos is...

I have no idea where to start with this one, let me try and find some notes on this...

Our lecturer has just tried to make it relevant/more difficult due to the fact that we are doing an engineering course.

After a bit of research I'm under the impression I need to use the formulae V= u + at S = ut + 1/2 at^2 V^2 = u^2 + 2as Also my error in that the position function should be (s) instead of (p)

Homework Statement A moving point has a position function (P) and is given by 2D quantities where the (Y) axis is affected by gravity (9.8m/s/s) and (t) is in seconds. X(t)=4t cos θ and Y(t)= 4t sin (θ)-5t^2 If θ = Pi /3 find the speed in directions after 10 seconds...
