What statement is true according to newton’s first law of motion? a. in the absence of unbalanced force an object at rest will stay at rest and an object in motion will come to a stop.

b. in the absence of an unbalanced force, an object will start moving and an object in motion will come to a stop.

c. in the absence of an unbalanced force, an object at rest will stay at rest and an object in motion will stay in motion.

d. in the absence of an unbalanced force, an object will start moving and an object in motion will stay in motion.

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
