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:
= 
On substituting the given values, we get
= 
= 
On converting it in "MJ", we get
= 
= 
Answer:
W = 5586[J]
Explanation:
Work in physics is defined as the product of force by a distance.
where:
W = work [J]
F = force = m*g [N]
m = mass = 300 [kg]
g = gravity acceleration = 9.81 [m/s²]
d = distance = 1.9 [m]
Now replacing:
![W=m*g*d\\W=300*9.81*1.9\\W=5586[J]](https://tex.z-dn.net/?f=W%3Dm%2Ag%2Ad%5C%5CW%3D300%2A9.81%2A1.9%5C%5CW%3D5586%5BJ%5D)
