The coordinates of an object moving in the xy plane vary with time according to the following equations. t is in seconds and ω has units of seconds -1. x = -(6.40 m) sin ωt
y = (4.00 m) - (6.40 m) cos ωt (a) Determine the components of velocity and components of acceleration at t = 0. (Use omega for ω.) (b) Write expressions for the position vector, the velocity vector, and the acceleration vector at any time t 0. (Use omega for ω and t as appropriate.)

Question

The coordinates of an object moving in the xy plane vary with time according to the following equations. t is in seconds and ω has units of seconds -1. x = -(6.40 m) sin ωt
y = (4.00 m) - (6.40 m) cos ωt (a) Determine the components of velocity and components of acceleration at t = 0. (Use omega for ω.) (b) Write expressions for the position vector, the velocity vector, and the acceleration vector at any time t > 0. (Use omega for ω and t as appropriate.)
