0Starting from rest, A lift moves up with an
P acceleration of \( 2 \mathrm{~ms}^{-2} \). In this lift, a ball is dropped
\( \mathrm{WV} \) from a height of \( 1.5 \mathrm{~m} \) (with respect to floor of lift). The time taken by the ball to reach the floor of the lift is \( \left(\mathrm{g}=10 \mathrm{~ms}^{-2}\right) \) :
(1) \( 0.3 \mathrm{~s} \)
(2) \( 0.2 \mathrm{~s} \)
(3) \( 0.16 \mathrm{~s} \)
(4) \( 0.5 \mathrm{~s} \)
