Question

a 2 kg body is sliding up an inclined plane of information 30 degree find the work done by the force of gravity in moving the body through 1 metre

Answer 1

1. Apply the work equation to determine the amount of work done by the applied ... Then calculate the work done by these forces. .... The block moves a horizontal distance of 3.0 m.

Answer 2

Hello buddy

Since gravity works vertically, we will only consider the vertical displacement
So if we draw a triangle in it and consider the vertical displacement as c
sin30=x/1
x=1/2

The weight of the object is 20 N
F=20N
s=1/2m

Work = F*s
= 20*1/2
=10J

The work done is 10 J.
