Question

speed of an object in circular motion reduces at the rate of 3m/s every second which is equal to its centripetal acceleration. What is the direction of resultant acceleration with x axis if centre of circular path is at the origin?

Answer 1

Explanation:

In uniform circular motion, angular velocity () is a vector quantity and is equal to the angular displacement (Δ, a vector quantity) divided by the change in time (Δ). Speed is equal to the arc length traveled (S) divided by the change in time (Δ), which is also equal to ||R.
