1.When Ox Tucker and his grandfather Smackie went fishing, Ox accidentally caught his hook on Smackieʼs Darth Vader helmet (mass = 1.20 kg) The helmet wouldnʼt break free so Ox spun it around in circles to try to break it loose. As it circled, the helmet made one revolution every 4.00 seconds and was at a distance of 7.00 meters from him.

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
