Question 1

Answer 1

Answer:

W = 600 J

Explanation:

We have,

According to attached figure,

Height of the inclined plane is 60 m

Force acting on the block is 10 N

It is required to find the work must be done against gravity to move it to the top of the incline. The work done is given by :

W = mgh

or

$W=F\times h\\\\W=10\times 60\\\\W=600\ J$

So, the work done against the gravity is 600 J.
