Chapter 5, Problem 45EAP

Problems 42 through 52 describe a situation. For each, draw a motion diagram, a force-identification diagram, and a free-body diagram.

42. An elevator, suspended by a single cable, has just left the tenth floor and is speeding up as it descends towards the ground floor.

43. A rocket is being launched straight up. Air resistance is not negligible.

44. A Styrofoam ball has just been shot straight up. Air resistance is not negligible.

45. You are a rock climber going upward at a steady pace on a vertical wall.

46. You’ve slammed on the brakes an your car is skidding to a stop while going down a 20° hill.

47. You’ve just kicked a rock on the sidewalk and it is now sliding along the concrete.

48. You’ve jumped down from a platform. Your feet are touching the ground and your kees are flexing as you stop.

49. You are bungee jumping from a high bridge. You are moving downward while the bungee cord is stretching.

50. Your friend went for a loop-the-loop ride at the amusement park. Her car is upside down at the top of the loop.

51. A spring-loaded gun shoots a plastic ball. The trigger has just been pulled and the bull is starting to move down the barrel. The barrel is horizontal.

52. A person on a bridge throws a rock straight down toward the water. The rock has just been released.

Part A What is the passenger's weight before the elevator starts moving? Express your answer with the appropriate units. Part B What is the passenger's weight while the elevator is speeding up? Express your answer with the appropriate units. Part C What is the passenger's weight after the elevator reaches its cruising speed? Express your answer with the appropriate units.
Two friends are sitting in a stationary canoe. At t = 3.0 s the person at the front tosses a sack to the person in the rear, who catches the sack 0.2 s later. Which plot given shows the velocity of the boat as a function of time? Positive velocity is forward, negative velocity is backward. Neglect any drag force on the canoe from the water.
13. The figure shows a block of mass M on an inclined plane at an angle 0 with respect to the horizontal. There is friction between the block and inclined plane. When released from rest, the block accelerates down the inclined plane and travels a distance d along the surface. What is the expression for the final velocity of the block at the end of the inclined plane? M 2gd(sino + 4gcosf0) a. b. 2gd(cos) +H;sin0) c. V2gd(sino - Hgcos0) d. V2gd(cos0 – Hsino) e. gdsine
