A merry-go-round rotates with a centripetal acceleration of 18 m/s^2. If the outer horses are 9 m from the center of the ride. What is their velocity? A. 12.7 m/s
B. 14.6 m/s
C. 16.3 m/s
D. 10.4 m/s

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.

What will a positive and a negative charge do if they are separated from each other?

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.
