PLEASE HELP ME IM GONNA DIE 49 POINTS A motorcycle cop with a radar gun spots a speeder doing 100 mph. The cop begins to accelerate just as the speeder goes by. The motorcycle can do zero to 100 km/h in 5.6s. How long will it take for the cop to catch up to the speeder and how fast will the cop being going when he catches up to the speeder?

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
