20. A body of mass 20kg lies on a horizontal floor
and is acted on by constant forces of
magnitudes 100N and mN in the directions
180° and 060° respectively, where m is a
constant. The body begins to move in the
direction 090°. If there is also a resistance of
per kg to the motion of the body,
(a) calculate the value of m and the magnitude
of the resultant force acting on the body.
(b) Find the acceleration of the body.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
