Question

It takes 27N of work to push a crate up a ramp to a dock. The ramp is 3 meters long. How much force is necessary?

PLEASE HELP

Answer 1

Solution:

Given,

Work = 27 N

Displacement = 3 m

According to question,

Force = ?

As we know,

Work = Force × Displacement

or, 27 = Force × 3

or, Force = 27/3

i.e, Force = 9 N
