MCQ (Single Correct Answer)
1
A block of mass 5 kg is kept on a smooth horizontal surface. A horizontal stream of water coming out of a pipe of area of cross-section $5 \mathrm{~cm}^{2}$ hits the block with a velocity of $5 \mathrm{~ms}^{-1}$ and rebounds back with the same velocity. The initial acceleration of the block is (density of water is $1 \mathrm{~g} / \mathrm{cc}$ )

A block is kept on a rough horizontal surface. The acceleration of the block increases from $6 \mathrm{~ms}^{-2}$ to $11 \mathrm{~ms}^{-2}$ when the horizontal force acting on it increases from 20 N to 30 N . The coefficient of kinetic friction between the block and the surface is
(acceleration due to gravity $=10 \mathrm{~ms}^{-2}$ )
