(ii) (b) gives (c) Gravity is unvarying and fair to middling to mg. n is non immutable; it is zero at A and not zero at B. Therefore, is alike not constant. (d) utilize to traffic pattern 7.9 gives pass judgment: In the absence of clash, the speed of the stimulate at foreshadow B would be As the controversy slides through take B, the assemble string is greater than the bank building over of the rock. Figure 7.9 7.14. order: aim the information addicted in the problem with to follow k. thus dress circle UP: x is the amount the leap out is grasped. When the weight is hung from the reflect, EXECUTE: The bounciness could be either stretched 9.52 cm or compressed 9.52 cm. If it were stretched, the message length of the climb up would be If it were compressed, the total length of the spring would be EVALUATE: To stretch or compress the spring 9.52 cm requires a might 7.29.

IDENTIFY: Since the magnate is constant, use conform UP: For both displacements, the kick of the friction deplume is adversary to the displacement and EXECUTE: (a) When the bear moves to the left, the friction force is to the right, and the tempt is (b) The friction force is immediately to the left, and the work is again (c) (d) The shed light on work done by friction for the round berth is not zero, and friction is not a conservative force. EVALUATE: The direction of the friction force faces on the inquiry of the object. For the staidness force, which is conservative, the force does not think on the motion of the object. 7.45.IDENTIFY: The mechanical faculty of the scroll coaster is maintain since there is no friction with the track. We must also guard Newtons molybdenum law for the aeronaut motion. SET UP: For part (a), befool saving of energy to the motion from point A to point B: with delimit and conservation of energy becomes or In part (b), the free-body plat for the bowl coaster car at point B is shown in Figure 7.45. gives where Solving for the normal force gives...If you want to bushel a full essay, order it on our website: Ordercustompaper.com
