Question

A block of mass 10 kg is placed on a rough surface
inclined plane of inclination 37° with horizontal. Now
the block is released. The work done by the gravitational
force and friction force, when the block moves from A to
B (sin 37° = 0.6, cos 37° = 0.8)
(1) 600 J, 160J
(3) 600 J, -160J
(2) -600 J, 160 J
(4) -600 J, -160 J​

Answer 1

Answer:

B option is correct

Explanation:

as no any height or coefficient of criction is given then it is a question of concept .

use sign convention to solve this question
