A car has run out of gas. Fortunately, there ia a gas station nearby. You must excert a force of 715 N on the car in order to move it. By the time you reach the station, you have done 2.72 x 10^4 J of work. How far have you pushed the car?

Sagot :

[tex]Work=Force(distance) \\ W=Fd \\ \frac{W}{F}=d \\ \\ \frac{2.72(10^4)}{715}=d \\ \\ \frac{27200}{715}=d \\ 38.04195804195804=d[/tex]

The car was pushed 38.04195804195804 (units is unknown)

Answer:

the distance that it will move is given by

d = 38 m

Explanation:

As we know that work done is defined by the product of force and displacement

So we will have

W = F .d

now we will have

F = 715 N

[tex]W = 2.72 \times 10^4 J[/tex]

now we have

W = F.d

[tex]2.72 \times 10^4 = 715 \times d[/tex]

[tex]d = 38 m[/tex

so the distance that it will move is given by

d = 38 m
