The small mass m 1.4 kg and big mass M= 9.5 kg are initially at rest with the small mass at the top of the inclined surface. The small mass will start sliding down the large mass M without friction. The large mass itself is also free to move on a frictionless horizontal surface. Given that h= 7.5 meter, what will the magnitude of the velocity of the mass M when it reaches the horizontal surface? Take g 9.81 m/s? Provide your answer with 2 decimal places. M
