Work varies directly with the distance an object moves. A
man uses a 32-kilogram push
lawn mower to mow his yard.
If the man pushes the lawn mower a
distance of 400 meters, how much work,
in joules, does the man do while mowing
his yard? (Hint: The weight of the lawn
mower is constant.)

125440J

Step-by-step explanation:

Given parameters:

 Mass of push  = 32kg

 Distance  = 400m

Unknown:

Work done by the man  = ?

Solution:

The work done is the product of force and distance;

       Work done  = force x distance

Here, the force applied is;

    Force  = mg  = 32 x 9. 8 = 313.6N

Now,

   Work done  = 313.6 x 400 = 125440J

not sure but it may be b, as i said i'm not sure.

1260=3*6*7*10=3^2*2^2*7*5 perfect cude = 3^3*2^
