Physics - W.E.P. Question with Solution | TestHub

A block of mass 10 kg is released on a fixed wedge inside a cart which is moved with constant velocity 10 m/s towards right. Take initial velocity of block with respect to cart to be zero. Then work done by normal reaction on block in two second in ground frame will be ( $\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2$ )
