A small block of mass m is pushed towards a movable wedge of mass `etam` and height h with initial velocity u.All surface are smooth. The minimum value of u for which the block will reach the top of the wedge:

A block of mass m is pushed towards a movable wedge of mass nm and height h , with a velocity u . All surfaces are smooth. The minimum value of u for which the block will reach the top of the wedge is

A block of mass m is pushed towards a movable wedge of mass nm and height h , with a velocity u . All surfaces are smooth. The minimum value of u for which the block will reach the top of the wedge is

A block of mass m is pushed towards the movable wedge of mass M and height h , with a velocity v_(0) . All surfaces are smooth . The minimum value of v_(0) for which the block will reach the top of the wedge is

A ball of mass 'm' is pushed with a velocity u towards a movable wedge of mass 3m which is at rest. Height of the wedge is 60m. Assume all surfaces to be smooth. The minimum value of 'u' for which the block will reach the top of the wedge is ( There is no loss of energy when the ball tries to rise on the wedge ) ( take g = 10 m//s^(2) )

A block of mass 1kg is pushed on a movable wedge of mass 2kg and height h=30cm with a velocity u=6m//sec . Before striking the wedge it travels 2m on a rough horizontal portion. Velocity is just sufficient for the block to reach the top of the wedge. Assuming all surfaces are smooth except the given horizontal part and collision of block and wedge is jerkless, the friction coefficition of the rough horizontal part is :

A block of mass 1kg is pushed on a non-movable wedge of mass 2kg and height h=30cm with a velocity u=6m//sec . Before striking the wedge it travels 2m on a rough horizontal portion. Velocity is just sufficient for the block to reach the top of the wedge. Assuming all surfaces are smooth except the given horizontal part and collision of block and wedge is jerkless, the friction coefficition of the rough horizontal part is :
