If half of the weight of a flatbed truck is supported by its two drive wheels, what is the maximum acceleration it can achieve o
Scilla [17]

Answer:

Maximum acceleration will be equal to 3.43m/sec^2

Explanation:

We have given coefficient of kinetic friction \mu _k=0.7

And coefficient of static friction \mu _s=1

Acceleration due to gravity g=9.8m/sec^2

When truck moves maximum force will be equal to F=\mu _kmg

It is given that half of the weight is supported by its drive wheels

So force required =\frac{\mu _kmg}{2}

From newtons law maximum acceleration will be equal to a=\frac{\frac{\mu _kmg}{2}}{m}=\frac{\mu _kg}{2}=\frac{0.7\times 9.8}{2}=3.43m/sec^2

Explain what forces are acting on an object that is decreasing in the speed​
pshichka [43]

Answer:

The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down. When objects move through a fluid, such as air or water, the fluid exerts a frictional force on the moving object. The frictional force from a fluid is called a drag force.

A 60.0-kg person rides in an elevator while standing on a scale. the scale reads 400 n. the acceleration of the elevator is clos
Keith_Richards [23]

Reading of the scale will be given as Normal force on the man

So here we can say that

weight of the mas will be

W = mg = 60*10 = 600 N

normal force on the man will be given as

F_n = 400 N

now net force is given by Newton's II law

F_{net} = ma

F_g - F_n = ma

600 - 400 = 60*a

a = \frac{200}{60} = \frac{10}{3}

a = 3.33 m/s^2

so elevator is accelerating downwards with an acceleration a = 3.33 m/s^2

Which number can each term of the equation be multiplied by to eliminate the fractions before solving? 6 – x + = 6 minus StartFr
zysi [14]

Answer:

We need to multiply 12 to each term to eliminate fractions.

Explanation:

Given expression:

6-\frac{3}{4}x+\frac{1}{3}=\frac{1}{2}x+5

To eliminate the fraction we need to multiply each term by least common multiple of the denominators of the fraction.

The denominators in the above expressions are:

4, 3 and 2

The multiples of each can be listed below.

2⇒ 2,4,6,8,10,<u>12</u>,14,16.....

3⇒ 3,6,9,<u>12</u>,15,18

4⇒ 4,8,<u>12</u>.......

From the list of the multiples stated, we can see the least common multiple is 12.

So we will multiply each term by 12.

Multiplying 12 to both sides.

12(6-\frac{3}{4}x+\frac{1}{3})=12(\frac{1}{2}x+5)

Using distribution,

72-9x+4=6x+60

Thus we successfully eliminated the fractions.
