1.	A smooth block of mass m moves up from bottom to top of a wedge which is moving with an acceleration `a_(10)`. Find the work done by the pseudo force measured by the person sitting at the edge of the wedge.
Answer» The observer moving with wedge will observe a pseudo force `ma_0` in the direction opposite to `veca_0`. ` ` Since `vecF_(ps)=-vecma_0` is a constant force, therefore, `W_(ps)=vecF_(ps)vecS=-(ma_0)lcos180^@=ma_0l`
