Trini has finished preschool for the day and her dad has come with a surprise. He has tied a 1.80 m rope to a cart to give her a spin in the cart (during which the rope is parallel to the ground). Together, Trini and the cart have a combined mass of 24 kg. Trini's 2 kg backpack is behind her in the cart. The friction between the wheels of the cart and the ground is negligible.

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

No. rocks can follow various pathways.
