A moving point has a position function (S) 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 1second
Find the angle where maximum X direction = maximum Y direction
Find the time for maximum x direction = maximum Y direction
Find the acceleration after 2 seconds
Does the acceleration vary against time?
Relevant equations/notes....
Use Equations of linear motion. Eg.
V= u + at
S = ut + 1/2 at^2
V^2 = u^2 + 2as
9.8m/s/s can be rounded to 10m/s/s for simplicity
