initially when small block m is at top then it is at rest so it's total mechanical energy is it's potential energy, if we take horizontal surface to be at 0 potential energy then total mechanical energy with respect to horizontal surface is = mgR
as height of m is R
velocity of m as it reaches horizontal surface = v
as
u is speed of M towards left and M moves a distance y towards left when m moves R towards right so that their center of mass does not move as there is no external force acting on the system
so M moves distance towards left
please rate it up thanks :)

Consider the small cube of mass m in the figure. It slides down a circular path of radius R carved into a large block of mass M. M rests on a table, and both blocks move without friction (i.e. M can easily slide sideways). The blocks are initially at rest, and m starts from the top of the path. Find the velocity of m as it leaves the block. Consider the small cube of mass m in the figure. It...
A small mass m slides without friction along the looped apparatus shown in Fig. 6-39. If the object is to remain on the track, even at the top of the circle (whose radius is r), from what minimum height h must it be released? (Answer in terms of r.)
5. A particle of mass m slides without friction and starting from rest down a block of mass M in which the surface is shaped into a quadrant of a circle of radius R. The block also slides without friction on a table top. Choose two suitable generalized coordinates a) Using the Lagrange-multiplier formalism, find the equations of motion of the mass and the block and the reaction force of the block on the mass (ie. the constraint force b)...
A block of ice of mass m and a wedge of ice of mass M can slide on one another and on a horizontal ice surface without friction. Initially the wedge is at rest and the block moves towards it with speed upsilon_0. When the block reaches the wedge, it slides up the slope to a maximum height, h above the horizontal. It then descends and returns to the horizontal surface. What is the height, h reached by the block?...
In the figure, a small block of mass m = 0.022 kg can slide along the frictionless loop-the-loop, with loop radius R = 15 cm. The block is released from rest at point P, at height h = 5R above the bottom of the loop. What are the magnitudes of (a) the horizontal component and (b) the vertical component of the net force acting on the block at point Q? (c) At what height h should the block be released...
A block of mass m starts from rest and slides down from the top of a wedge of height h and length d. The surface of the wedge forms an angle of ? with respect to the horizontal direction. The force of kinetic friction between the block and the wedge is f. How fast is the block traveling when it reaches the bottom of the wedge?
Question 12 of 14 > Final position A small block of mass m slides to the left on a frictionless, horizontal surface with speed u.

5. A small mass m starts from rest and slides from the top of a fixed sphere of radius r. (a) If the sphere is frictionless, at what angle θ from the vertical does the mass leave the surface?

(c) The mass is now placed just past this...
Problem 4 A block of mass m slides at velocity vo across a horizontal frictionless surface toward a large curved movable ramp n and has a smooth circular frictionless face up which the block can easily slide.

take r ro be 1.0 m 1. A small block of mass 0.5 kg compresses a spring (K 500 N/m) a distance of x 0.50 m. The block is released from rest and travels along a frictionless, horizontal surface until it reaches point A.
