If the distance from A to B os 120(km)by current road and in a straight line is 30(km), the difference between the average speed and the modulus of the average speed of a movile that takes 1.5 hours to take the tour

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

Newton's first law describes something special that results from the sum of all the external forces (including gravity) on an object.
