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...
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...
