A person tries to lift each object with a force of 18 N, upward. Which statement is supported by the data in the table?
O A. All of the objects will move, and object 2 will accelerate upward
the fastest
B. None of the objects will move, but the normal force on all of the
objects will increase.
c. Objects 1 and 2 will not move, and objects 3 and 4 will accelerate
upward.
D. Objects 1 and 2 will move downward, and objects 3 and 4 will
move upward.

A33.1 g copper object is launched from a 1.5 m 30° steel incline positioned on the floor by being pulled up a string attached to a 50.0 g mass suspended vertically over a pulley. the object is projected towards a glass table where it lands when it is at the point along its trajectory with the lowest speed. it comes to a halt when it clears the opposite edge of the table. it then falls and lands on 9 physics texts each 5 cm thick that are stacked on the floor on the opposite side of the table. assume that the table does not have a ledge and the rectangular object experiences 0.05 n of air resistance as it falls towards the books. how far and how long did the object travel and how fast does it hit the books. assume that at the moment the copper object leaves the incline, the massless string and ideal pulley break off

How much force was applied to an object if was moved 2 meters and the work done on the object was 8 joules? a. 0.25 n b. 4 n c. 6 n d. 16 n
