Question

A body slides down a smooth inclined plane of height h and angle
of inclination 30° reaching the bottom with a velocity v. Without
changing the height, if the angle of inclination is doubled, the ve-
locity with which it reaches the bottom of the plane is
explanation also​

Answer 1

Explanation:

the final velocity of the body is obtained using conservation of energy. it is irrespective of the path traveled

1/2 * mv²= mgh

therefore v is proportional to √h

if h is doubled, v becomes √2 times.

hence new velocity will be v√2

Answer 2

Answer:

Ashmiya,,,,please focus on question

Explanation:

how without changing height ,we can change angle
