363155 The apparent weight of a person inside a lift is \({W_1}\) when lift moves up with a certain acceleration and is \({W_2}\) when lift moves down with same acceleration. The weight of the person when lift moves up with constant speed is:

363156 Assertion :
In downward accelerated motion of lift, apparent weight of a body decreases.
Reason :
When the lift moves with uniform velocity the man in the lift will feel weightlessness.

363157 A block of mass \(15\;kg\) is placed at a distance of \(10\;m\) from the rear end of a long trolley as shown in figure. The coefficient of friction between the block and the surface below is \(0.4.\) Starting from rest, the trolley is given a uniform acceleration of \(5\;m{\rm{/}}{s^2}.\) At what distance (in metres) from the starting point will the block fall-off the trolley? (Take \(g = 10\;m{\rm{/}}{s^2}\))

363158 A lift moving upwards with a velocity \(5\,m/s\) is stopped by uniform retardation in 5 \(s\). The apparent weight of a man of mass 60 \(kg\) before stopping will be (take \(g = 10\,m/{s^2}\))

363159 A block of mass 1 \(kg\) rests inside a cubical vessel, as shown in the figure. Which is moving with a velocity of \(v = \sqrt {29} \,t\,\,m/s\) where \(t\) is in sec. All the surfaces are smooth. The block is at rest w.r.t, the cube, what is the total force exerted by the cube on the block?
