A car traveling at a velocity of 40 m/s accelerates at 5 m/s/s for 10 seconds. What is the car's final velocity?
Papessa [141]

Answer:

<h3>The answer is 90 m/s</h3>

Explanation:

To find the final velocity of an object given it's initial velocity , time taken and it's acceleration we use the formula

<h3>v = u + at </h3>

where

v is the final velocity

u is the initial velocity

t is the time taken

a is the acceleration

From the question

u = 40 m/s

t = 10s

a = 5 m/s²

We have

v = 40 + 5(10) = 40 + 50

We have the final answer as

<h3>90 m/s</h3>

Hope this helps you

The kinetic friction coefficient between a cabinet and the floor is 0.3. Mass of the cabinet is 300kg. A man pushes the cabinet
podryga [215]

Answer:

<h2>0.39m/s^2</h2>

Explanation:

Step one:

given data

mass m= 300kg

applied force F= 1000N

coefficient of friction μ= 0.3

Step two:

The net force Fn= applied force-friction force  

Fn=F-F1

F1= limiting force

F1=μ*m*g

F1=0.3*300*9.81

F1=882.9N

the Net force= 1000-882.9

Fn=117.1N

Step three:

we know that

F=ma

Fnet=ma

a= Fnet/m

a=117.1/300

a=0.39m/s^2

The internal energy of nmoles of an ideal gas depends on a. one state variable T.
VMariaS [17]

Answer:

Correct option a. one state variable T.

Explanation:

In the case of an ideal gas it is shown that internal energy depends exclusively on temperature, since in an ideal gas any interaction between the molecules or atoms that constitute it is neglected, so that internal energy is only kinetic energy, which depends Only of the temperature. This fact is known as Joule's law.

The internal energy variation of an ideal gas (monoatomic or diatomic) between two states A and B is calculated by the expression:

ΔUAB = n × Cv × (TB - TA)

Where n is the number of moles and Cv the molar heat capacity at constant volume. Temperatures must be expressed in Kelvin.

An ideal gas will suffer the same variation in internal energy (ΔUAB) as long as its initial temperature is TA and its final temperature TB, according to Joule's Law, whatever the type of process performed.
