Unformatted text preview: d. 2. vt = g / k 3. vt = g / k 4. vt = 0 Answer 3. When the raindrop approaches terminal speed, the rate of change of the speed approaches zero, so g ! k v 2 " 0 , v ! vt = g / k . Question 2 A particle, starting at rest at t = 0 , experiences a non-constant acceleration ax (t ) . It’s change of position can be found by 1) Differentiating ax (t ) twice. 2) Integrating ax (t ) twice. 1 3) ax (t )t 2 . 2 4) None of the above. 5) Two of the above. Answer 2. The change in x-component of the velocity for an interval [ 0, t ] is the integral of the x-component of acceleration with respect to time, vx (...
