The coordinates of an object moving in the xy plane vary with timeaccording to the equations
x = -7.8 sin ?t and y = 4.00 - 7.8 cos ?t,
where ? is a constant, x and y are in meters, and t is inseconds.
(a) Determine the components of velocity of the object at t = 0.(Use the following as necessary: ?.)
= m/s
(b) Determine the components of the acceleration of the object at t= 0. (Use the following as necessary: ?.)
= m/s2
(c) 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 ? and t.)
= m
= m
= m
