Chapter 5: Q 73P (page 122)

In Fig. 5-61, a tin of antioxidants (m1=1.0kg)on a friction less inclined surface is connected to a tin of corned beef(m2=2.0kg).The pulley is mass less and friction less. An upward force of magnitudeF=6.0Nacts on the corned beef tin, which has a downward acceleration of5.5m/s2. What are (a) the tension in the connecting cord and (b) angle 尾?

Short Answer

Expert verified
a)The tension in the connecting rod is T=2.6N

b)Angle is 尾=17鈭�

Step by step solution

01

Given information

Given that,

m1=1.0kg

role="math" localid="1655520757224" m2=2.0kg

role="math" localid="1655520811170" F=6.0N

a=5.5m/s2

02

Determining the concept

The problem is based on Newton鈥檚 second law of motion which states that the rate of change of momentum of a body is equal in both magnitude and direction of the force acting on it.

Formula:

According to the Newton鈥檚 second law of motion,

Fnet=鈭�Ma

03

(a) Determining the tension in the connecting rod

Free Body diagram

T+m1gsin尾=m1a

m2g-F-T=m2a(2脳9.8)-6-T=2脳5.5

By solving for above equation,

T=2.6N

Hence, the tension in the connecting rod isT=2.6N

04

(b) Determining the angle

Now, plugging this value in equation 1,

2.6+1脳9.8脳sin尾=1脳5.5尾=17鈭�

Hence, an angle is尾=17鈭�

In Fig. 5-21, forcesF鈫�1andF鈫�2are applied to a lunchbox as it slides at constant velocity over a frictionless floor. We are to decrease angle胃without changing the magnitude ofF鈫�1. For constant velocity, should we increase, decrease, or maintain the magnitude ofF鈫�2?

A customer sits in an amusement park ride in which the compartment is to be pulled downward in the negative direction of a yaxis with an acceleration magnitude of1.24g, withg=9.80m/s2. A 0.567gcoin rests on the customer鈥檚 knee. Once the motion begins and in unit-vector notation, (a) what is the coin鈥檚 acceleration relative to the ground and (b) what is the coin鈥檚 acceleration relative to the customer? (c) How long does the coin take to reach the compartment ceiling,2.20mabove the knee? In unit-vector notation, (d) what is the actual force on the coin and (e) what is the apparent force according to the customer鈥檚 measure of the coin鈥檚 acceleration?

Figure 5-28 shows four choices for the direction of a force of magnitude F to be applied to a block on an inclined plane. The directions are either horizontal or vertical. (For choice b, the force is not enough to lift the block off the plane.) Rank the choices according to the magnitude of the normal force acting on the block from the

plane, greatest first.

Figure 5-19 gives the free-body diagram for four situations in which an object is pulled by several forces across a frictionless floor, as seen from overhead. In which situations does the accelerationa鈫�of the object have (a) an x component and (b) a y component? (c) In each situation, give the direction ofby naming either a quadrant or a direction along an axis. (Don鈥檛 reach for the calculator because this can be answered with a few mental calculations.)

Figure 5-27 shows three blocks being pushed across a frictionless floor by horizontal forceF鈫�. What total mass is accelerated to the right by (a) forceF鈫�, (b) forceF鈫�21on block 2 from block 1, and (c) forceF鈫�32on block 3 from block 2? (d) Rank the blocks according to their acceleration magnitudes, greatest first. (e) Rank forcesF鈫�,F鈫�21andF鈫�32, and according to magnitude, greatest first.
