Figure (9-E11) shows a small block of mass m which is started with a speed v on the horizontal part of the bigger block of mass M placed on a horizontal floor. The curved part of the surface shown is semicircular. All the surfaces are frictionless. Find the speed of the bigger block when the smaller block reaches the point A of the surface. |

Answer» THANKS for asking the question! ANSWER:: As the small body of MASS m is started with a velocity V in the horizontal DIRECTION. So , the total initial momentum at initial position in horizontal direction will continue to remain same as the total momentum at point A on bigger BLOCK is in horizontal direction. So, mv + M x 0 = (m + M)V V = mv / (M+m) Hope it helps! |
