Question

How much work (MJ) must a car produce to drive 125 miles if an average force of 306 N must be maintained to overcome friction?

Answer 1

The right solution is "61.557 MJ". A further explanation is given below.

Step-by-step explanation:

The given values are:

Force,

F = 306 N

Drive,

D = 125 miles,

i.e.,

= 201168

meters

As we know,

The work done will be:

=
`F* S`

On substituting the given values, we get

=
`306* 201168`

=
`61557408 \ J`

On converting it in "MJ", we get

=
`61.557* 10^6 \ J`

=
`61.557 \ MJ`
