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 β?

Short Answer

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

b)Angle is β=17

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’s 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’s second law of motion,

Fnet=Ma

(a) Determining the tension in the connecting rod

Free Body diagram

T+m1gsinβ=m1a

m2g-F-T=m2a(2×9.8)-6-T=2×5.5

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+1×9.8×sinβ=1×5.5β=17

Hence, an angle isβ=17

In earlier days, horses pulled barges down canals in the manner shown in Figure. Suppose the horse pulls on the rope with a force of7900Nat an angle of θ=18°to the direction of motion of the barge, which is headed straight along the positive direction of an xaxis. The mass of the barge is9500kg, and the magnitude of its acceleration is 0.12m/s2. (a) What is the magnitude and (b) What is the direction (relative to positive x) of the force on the barge from the water?

A 1400 kgjet engine is fastened to the fuselage of a passenger jet by just three bolts (this is the usual practice). Assume that each bolt supports one-third of the load. (a) Calculate the force on each bolt as the plane waits in line for clearance to take off. (b) During flight, the plane encounters turbulence, which suddenly imparts an upward vertical acceleration of2.6m/s2to the plane. Calculate the force on each bolt now.

Three astronauts, propelledby jet backpacks, push and guide a 120 kg asteroid toward a processing dock, exerting the forces shown inFig. 5-29, with F1=32N,F2=55N,F3=41N,θ1=30°,and .What is the asteroid’s acceleration(a) in unit-vector notation and as (b) a magnitude and (c) a direction relative to the positive direction of the x axis?

Figure shows a 5.00 kgblock being pulled along a frictionless floor by a cord that applies a force of constant magnitude20.0Nbut with an anglethat varies with time. When angle θ=25.0°, (a) at what rate is the acceleration of the block changing ifθ(t)=(2.00×10-2deg/s)t-2and (b) at what rate is the acceleration of the block changing if θ(t)=(2.00×10-2deg/s)t?

(Hint:The angle should be in radians.)

There are two forces on the2.00kgbox in the overhead view of Figure, but only one is shown. For F1=20.0N,a=12.0m/s2 , and θ=30.0° , find the second force

(a) in unit-vector notation and as

(b) a magnitude of second force and

(c) an angle relative to the positive direction of the xaxis
