An object moves at a constant speed along a circular path in a horizontal XY plane. With the center at the origin. When the object is at x=−2m, its velocity is −(4m/s) j^.What is the object's acceleration when it is y=2m?

Answer:

Velocity, v = −(4m/s) j^.

at y = 2, centripetal acceleration magnitude,

a =  \frac{v {}^{2} }{r}  \\  =  \frac{(4) {}^{2} }{2}  \\  =  \frac{16}{2}  = 8m {}^{2} .

So, ar = −(8m/s 2 )j^.
