# The work needed to move a mass of 5.41 kg 39.5 m

## Homework Statement

The work needed to move a mass of 5.41 kg 39.5 m against a resistive force of 24.9 N is _____J.

W = F x d

## The Attempt at a Solution

F=ma
Fapplied - Resistive Force = 5.41(a)

Welcome to PF;
F=ma
Fapplied - Resistive Force = 5.41(a)
I don't know what you mean by "(a)" in there. It looks like you are trying to calculate a force and you have noticed that you do not know the acceleration.

The work is the magnitude of the applied force multiplied by the distance moved in the direction of the applied force.

In the problem, you are told there is a "resistive" force - maybe that is the wind pushing on the object.
In order to move the object "against the wind", what is the minimum applied force that is needed?

It's hard for me to explain due to the question only being worded like that in my homework assignment.
I meant 'a' as in acceleration. I am completely unaware of how to find the minimum applied force.
