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?

baherus [9]

Answer:

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

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:

= $F\times S$

On substituting the given values, we get

= $306\times 201168$

= $61557408 \ J$

On converting it in "MJ", we get

= $61.557\times 10^6 \ J$

= $61.557 \ MJ$
