Thanks . Sir...

My question is that there is a stationary wedge on which block is placed and all the sutfaces are smooth.Now according to mg physics teacher the acceleration of block with respect to wedge is gsin@ and with respect to ground is g .Is it true.But according to my knowledge as we read that...

Here wedge is stationary.Now please tell me the acceleration of block with respect to wedge and ground.

Hi friendz I have a problem. If a block of mass m is placed over the wedge such that there is no friction then what is the acceleration of block 1with respect to wedge 2 with respect to ground Pleas reply. Thanks in advance. My sir said that it is different.Is it so.

Hello friends I have a problem.please give me the answer. Two blocks of masses 6kg and 4kg connected by a rope are resting on frictionless floor.If an instantaneous force of 60N is applied to 6kg block for only a second.Then what is the acceleration of the first and second block.Is the...

Thanks a lot...

On what factor the transference of kinetic energy from one body to another body depends on colliding bodies.

O.K sir I got the point.And thanks for reply on my questions.Thank you very... much

But as we know that when we kick a football with a force f (such that mass of foot is M then in opposite it gives us reaction but when a box of same mass M collide with a body of mass M/2 and apply a force F then it does not get equal reaction because if it gets equal reaction then it must stops...

sir please read this two examples- when you and your friend sit on two.chairs (both of same mass)and you push your friend's forward then you got equal and opposite force in backward direction.but when a body of mass m strikes with a body of same mass m it stops why.another w example when you...

sir please tell me how it works in third case

If a body of mass m collides with a wall it changes its direction because when it collides with wall it transfer its energy to the wall but due to wall's elastic nature it transfer its energy back to a body due to which it get reaction and when it collides with a body of same mass then on...

Hi friendz I m new to this forum I have a problem in a question which is as follows- If a body of mass m collides with a body of mass 2m it changes its direction of motion buy when it collides with a body of same mass m it stops and when it collides with a body of mass m/2 it does not change...
