While mowing your lawn, you push a lawnmower 120. m with a constant force of 300. n. how much work have you done, assuming that all force is in the same direction as the direction of motion? express your answer in scientific notation.

a)2.5 x 101 j
b)2.50 x 101 j
c)3.6 x 104 j
d)3.60 x 104 j

Write the equation for momentum, first using symbols for the variables, then using words for the variables.
