Consider the following statements regarding motions in machines:

1). Tangential acceleration is a function of angular velocity and the radial acceleration is a function of angular acceleration.

2). The resultant acceleration of a point \(A\) with respect to a point \(B\) on a rotating link is perpendicular to \(A B\).

3). The direction of the relative velocity of a point \(A\) with respect to a point \(B\) on a rotating link is perpendicular to \(A B\).

Which of these statements is/are correct?

(a) 1 alone

(b) 2 and 3

(c) 1 and 2

(d) 3 alone.
