2) In coming to a stop, a car leaves skid marks on a road that are 40 m long. Assuming an acceleration of -8.0 m/s², was car was exceeding the 40 m/s
speed limit before braking. Indicate YES (the car was speeding) or NO (car
was not speeding) and justify your answer with a calculation.

The answer is c hope this

Then the answer would be d then

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
