A block of mass 1 kg is kept on the tilted floor of a lift moving down with $3 m / s^{2}$ . If the block is released from rest as shown what will be the time (in sec) taken by block to reach the bottom ?

Answer:

1.00

Solution:

$g_{e ff} = g - 3 = 7 m / s^{2}$

Resolve $g_{e ff}$ along the smooth inclined floor shown.

$s = \frac{1}{2} a t^{2}$

Substitution from the figure gives t = 1 s.
