Question

You push your physics book 1.2 m along a horizontal tabletop with a horizontal push of 10 N while the opposing force of friction is 5.9 N. Find the work done by the force of 10 N push.

the work done on the book by the force of friction.
the work done on the book by the force of gravity.

Answer 1

Step-by-step explanation:

Given that,

Distance = 1.2 m

Force = 10 N

Friction force = 5.9 N

We need to calculate the work done by the force of 10 N

Using formula of work done

`W = F\cdot d`

Put the value into the formula

`W=10*1.2`

`W=12\ J`

We need to calculate the work done by the force of friction

`W=5.9*1.2`

`W=7.08\ J`

We need to calculate the work done by the force of gravity

As there is no vertical force act on the book .

So, The work done will be zero.

Hence, The is the required solution.
