An object accelerates 1.3 m/s2 when a force of 3.7 newtons is applied to it. What is the mass of the object?
bezimeni [28]

Answer:

<h3>The answer is 2.85 kg</h3>

Explanation:

The mass of the object can be found by using the formula

m =  \frac{f}{a}  \\

f is the force

a is the acceleration

From the question we have

m =  \frac{3.7}{1.3}  \\  = 2.846153...

We have the final answer as

<h3>2.85 kg</h3>

Hope this helps you

O D. Both objects won't move at all. They will just stay where they were released.
astraxan [27]

Answer:

Do not see a picture or graph but suspect it would show the golf ball falling faster and striking the ground slightly before the soccer ball.

Probably D:  Soccer ball was affected by air resistance more than the golf ball.

Explanation:

Even though heavier, friction loss of the greater surface area soccer ball will counter pull of gravity more than the compact golf ball.

In a vacuum, (no friction) both objects fall at the same rate regardless of mass.

The x and y components of vector S are -30.0 m and +40.0 m, respectively. Find the magnitude of S and the angle between the dire
34kurt

Answer:

The given vector can be represented in unit vector as

\overrightarrow{w}=-30\widehat{i}+40\widehat{j}

The magnitude of any vector \overrightarrow{r}=u\widehat{i}+v\widehat{j} is given by

|w|=\sqrt{u^{2}+v^{2}}

Applying values we get

|w|=\sqrt{-30^{2}+40^{2}}\\\\|r|=50

We know that positive x axis in vertorial form is represented as

\overrightarrow{r}=\widehat{i}

taking dot product of both the vector's we get

\overrightarrow{r}.\overrightarrow{w}=|r||w|cos(\theta )\\\\\therefore cos(\theta )=\frac{(-30\widehat{i}+40\widehat{j}).\widehat{i}}{50}\\\\\therefore \theta =cos^{-1}(\frac{-30}{50})=126.86^{o}

So far, you’ve been working with an "ideal" pulley system. How do you think real pulley systems are different, and how would tha
almond37 [142]

Answer:

In an ideal pulley system is assumed as a perfect system, and the efficiency of the pulley system is taken as 100% such that there are no losses of the energy input to the system through the system's component

However, in a real pulley system, there are several means through which energy is lost from the system through friction, which is converted into heat, sound, as well as other forms of energy

Given that the mechanical advantage = Force output/(Force input), and that the input force is known, the energy loss comes from the output force which is then reduced, and therefore, the Actual Mechanical Advantage (AMA) is less than the Ideal Mechanical Advantage of an "ideal" pulley system

The relationship between the actual and ideal mechanical advantage is given by the efficiency of the pulley system as follows;

Efficiency \, \% = \dfrac{AMA}{IMA}  \times 100
