A block of mass `m` is released from the top of a mooth inclined plane of height `h` its speed at the bottom of the plane is proportion toA. `m^(0)`B. `m`C. `m^(2)`D. `m^(-1)` |
|
Answer» Correct Answer - A Let `v` be the speed of the object at the bottom of the plane According to work energy therem `W = Delta K = K_(f) - K_(i)` `mgh = (1)/(2) mv^(2) - (1)/(2) mv^(2) ( because u = 0)` `mgh= (1)/(2) mv^(2) (because u = 0)` `or v = sqrt(2gh)` From the above experession it is clear the `v` is independent of the mass of an object |
