A jet of water with a velocity of \(5 \mathrm{~m} / \mathrm{s}\) has an area of \(0.05 \mathrm{~m}^{2}\). It strikes a \(1 \mathrm{~m}\) thick concrete block at a point \(2 \mathrm{~m}\) above the ground (Figure P3.20). After hitting the block, the water drops straight to the ground. What minimum weight must the block have in order not to tip over?
