Answer:

The kinematics equations describe the motion of an object undergoing constant acceleration

Explanation:

The kinematics equations describe the motion of an object undergoing constant acceleration. These equations relate the variables of time, position, velocity and acceleration of a moving object, allowing any of these variables to be solved for if the others are known

Answer:

Explanation:

Givens

vi = 50 m/s

vf = 0

a = - 9.81

t = ?

Formula

t = (vf - vi)/a

Solution

t = (0 - 50)/-9.81

t = 5.097

Notice that a is made into a minus. It does not mean subtract. It means that the direction of the projectile and gravity must go in opposite directions. You will find that direction is a critically important consideration in physics.

Answer:

It'd take it 5.10 seconds

Explanation:

At the top of the launch, it is maximum height, h

formular derivation :

At maximum height, final velocity, v is zero

From first newtons equation:

[tex]{ \sf{v = u + gt}}[/tex]

v is the final velocity

u is the initial velocity

g is acceleration due to gravity

t is the time taken

but v is zero:

[tex]0 = u + gt \\ gt = u \\ t = \frac{u}{g} [/tex]

since it is vertical motion, u = usin(theta), where angle is 90°

[tex]{ \boxed{t = \frac{u \sin( \theta) }{g} }}[/tex]

t is the time taken to reach the top of the launch:

substitute, taking g to be 9.8 m/s²

[tex]t = \frac{50 \times \sin(90 \degree) }{9.8} = \frac{50}{9.8} \\ \\ { \boxed{ \boxed{time = 5.10 \: seconds}}}[/tex]

Fun Fact: Peanuts aren’t technically nuts

Answer:

W = F × d

W = 1 × 1

W = 1 Joule

step by step explanation

An apple is having a force of 1 N and it travels to a distance of 1 m then the work done on the apple by the force of gravity will be equal to 1 J.

Work is a physics term used to describe the transfer of energy that occurs when an object changes above a distance because of an external force, at least some of which is given in the vector of the dislocation. The element of the strong acting all along the path multiplied by the length of the path can be used to calculate work if the force is constant.

Mathematically, this idea is expressed as W = fd, where W is the effort and f is the force multiplied by d, the distance. Work is completed whenever the pressure is applied at an angle with regard to displacement.

As per the given information in the question,

Force, f = 1 N

Distance, d = 1 m

Then, the work done will be,

W = fd

W = 1 × 1

W = 1 J.

Answer: Dog's speed = (20 + 35) /12 = 4.583 m/s

Dog's velocity = (20-35)/12 = -1.25 m/s

Explanation: Speed is a scalar quantity so we don't care about direction which means we add the magnitude of both the directions i.e. east and west.

About the velocity, it's a vector quantity. So, we must be very careful with the directions and signs. In cartesian coordinates system, we generally take the right side of origin as the positive x-axis and the left side of origin as the negative x-axis. So, considering the same fact, we consider east as positive side and west as the negative side.

Therefore, when we add 20m + (-35m), we get = -15m and you already have the time period of  12 s.

Have a great day!

When converting all the given speeds to km/h and after comparing them, we have that the greatest is option 2: 10 m/s.

To find which of the given speeds is greatest, we need to convert all the units to km/h so we can compare the values.

[tex]v = 10 \frac{m}{s}*\frac{1 km}{1000 m}*\frac{3600 s}{1 h} = 36 km/h[/tex]

[tex]v = 10 \frac{ft}{s}*\frac{1 km}{3280.8 ft}*\frac{3600 s}{1 h} = 11.0 km/h[/tex]

[tex]v = 10 \frac{mi}{h}*\frac{1 km}{0.6214 mi} = 16.1 km/h[/tex]

[tex]v = 10 \frac{yd}{s}*\frac{1 km}{1093.6 yd}*\frac{3600 s}{1 h} = 32.9 km/h[/tex]

Therefore, the greatest speed is option 2: 10 m/s.

Answer: As the temperature increases, the flow time increases.

Explanation: i took the test

The relationship between the variables on this graph is that As the temperature increases, the flow time increases, therefore the correct answer is option B.

It is a scale of temperature used to measure the temperature, the kelvin scale of temperature is also known as the absolute scale of temperature.

The Standard International unit of thermodynamic temperature is the kelvin, often known less frequently as the degree Kelvin. The formal definition of one kelvin is 1/273.16  of the thermodynamic temperature of pure water's triple point.

As shown in the graph as the temperature increase across the X axis the flow time is increasing as well, these two variables are directly proportional to each other.

Thus, The graph shows a link between the variables, showing that when the temperature rises, flow time also rises, hence option B is the proper response.
