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)hatj`. What is the object's acceleration when it is `y=2m`

Text Solution

Verified by Experts

The correct Answer is:
(a)`-(4m//s)hati;` (b) `-(8m//s^(2))hatj`
