Chapter 5: Q.13b (page 128)

FIGURE EX5.13 shows an acceleration-versus-force graph for a 500gobject. What acceleration values go in the blanks on the vertical scale?

Short Answer

Expert verified

a.The acceleration of the object is2.0m/s2.

Step by step solution

01

Part.a.

Newton's second law states that the acceleration acting on an object is directly proportional to the force acting on the object and inversely proportional to the mass of the object.

a=Fm

Here, Fis the force acting on the object, and mis the mass of the object.

02

Step.2

The figure is shown below

From the figure at point(a), the force is2N

Convert the unit of mass fromto

m=500g10鈭�3kg1g=500脳10鈭�3kg

Substitute 2Nfor F, and 500脳10鈭�3kgfor m.

a=2N500脳10鈭�3kg=4.0m/s2

Therefore, the acceleration of the object is4.0m/s2.

03

Part.b.

From the figure at point (b), the force is1N

The acceleration acting on the object is,

a=Fm

Substitute 1Nfor F, and 500脳10鈭�3kgfor m.

a=1N500脳10鈭�3kg=2.0m/s2

Therefore, the acceleration of the object is2.0m/s2.

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

You are bungee jumping from a high bridge. You are moving

downward while the bungee cord is stretching.

Problems 35 through 40 show a free-body diagram. For each:

a. Identify the direction of the acceleration vector au and show it as a vector next to your diagram. Or, if appropriate, write a鈫�=0鈫�

b. If possible, identify the direction of the velocity vector v鈫�and show it as a labeled vector.

c. Write a short description of a real object for which this is the

correct free-body diagram. Use Examples 5.4, 5.5, and 5.6 as

models of what a description should be like.

A rubber ball bounces. We鈥檇 like to understand how the ball bounces. a. A rubber ball has been dropped and is bouncing off the floor. Draw a motion diagram of the ball during the brief time interval that it is in contact with the floor. Show 4 or 5 frames as the ball compresses, then another 4 or 5 frames as it expands. What is the direction of a u during each of these parts of the motion? b. Draw a picture of the ball in contact with the floor and identify all forces acting on the ball. c. Draw a free-body diagram of the ball during its contact with the ground. Is there a net force acting on the ball? If so, in which direction? d. Write a paragraph in which you describe what you learned from parts a to c and in which you answer the question: How does a ball bounce?

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