Question

. A lift of mass 7000kg is at rest. Find its apparent weight when the
i) lift is accelerating up with acceleration of 2 m/s?
ii) lift is accelerating down with acceleration of 4 m/s? (Take
g = 10m/s)​

Answer 1

Answer:

1) W= m(g+a) = 7000×12 = 84000kg.

2) W = m(g-a) = 7000×6 = 42000kg.
