Question

In the adjoining figure, a wedge is fixed to an elevator moving upwards with an acceleration a. A block of mass m is placed over the wedge. Find the acceleration of the block with respect to wedge. Neglect friction.

Answer 1

Answer:

Acceleration of total system = (g + a)

When system is at rest,

    Accⁿ of the block with respect to the wedge = mgsinΘ

∴ Required accⁿ = m(g + a)sinΘ                       Ans.

Answer 2

Acceleration of total system = (g + a)

When system is at rest,

   Accⁿ of the block with respect to the wedge = mgsinΘ

∴ Required accⁿ = m(g + a)sinΘ                       Ans.
