Physics question, I'm having trouble with a X,Y plane and equations.?
x = −5.63 sin ωt and y = 4.00 − 5.63 cos ωt,
where ω is a constant, x and y are in meters, and t is in seconds.
Write expressions for the position vector, the velocity vector, and the acceleration vector of the object at any time t > 0. (Use the following as necessary: omega for ω and t.)
r= -5.63sin(ωt) + (4-5.63cos(ωt))
v= 1st derivative, -5.63ωcos(ωt)+5.63sinω(ωt)
a= 2nd 5.63ω^2sin(ωt)+5.63cosω^2(ωt)
What am I doing wrong here?
