Question

A particle, starting at rest at t = 0, experiences a non-constant acceleration a,(t). It's change of position can

be found by:

(1) Differentiating ax(t) twice with respect to time

(2) Integrating ax(t) twice with respect to time

(3) = {ax (t)}1²

(4) None of these​

Answer 1

Answer:

(1) Differentiating ax(t) twice with respect to time

Answer 2

The correct answer will be option b.

•When we have to find acceleration from position then the steps will be

1) To differentiate the equation of position in order to get velocity.

2)To differentiate the equation of velocity to get acceleration.

•When we have to find position from acceleration the steps will be

1) To integrate equation of acceleration in order to get velocity

2)To further integrate equation of velocity to get the position.
