A) a boy is riding on a merry-go-round that rotates at a constant speed. if the merry-go-round makes 3.0 revolutions in 6.0 seconds. what is its angular speed in revolutions/second and in radians/second?

Aparticle moves in the xy plane with constant acceleration. at time zero, the particle is at x = 6 m, y = 8.5 m, and has velocity ~vo = (9 m/s) ˆı + (−2.5 m/s) ˆ . the acceleration is given by ~a = (4.5 m/s 2 ) ˆı + (3 m/s 2 ) ˆ . what is the x component of velocity after 3.5 s? answer in units of m/s.
