Answer:

1000kg

Explanation:

We can use the equation "p=mv"

p is the momentum in kg m/s
m is the mass measured in kg
v is the velocity measured in m/s

If we rearrange the equation to find mass (m), then the equation becomes:

m=p/v

We can substitute in the values of p and v as they are already given in the question.

p=25,000 kg m/s
v= 25 m/s

So, now we just substitute in the values to get our answer.

m=p/v

m=25,000/25

m=1000kg

Nataly_w [17]

The equilibrium condition allows finding the result for the force that the chair exerts on the student is:

The reaction force that the chair exerts on the student's support is equal to the student's weight.

Newton's second law gives the relationship between force, mass and acceleration of bodies, in the special case that the acceleration is is zero equilibrium condition.

∑ F = 0

Where F is the external force.

The free body diagram is a diagram of the forces on bodies without the details of the shape of the body, in the attached we can see a diagram of the forces.

Let's analyze the force on the chair.

$N_{chair} - W_{chair} - W_{student} = 0 \\ \\N_{chair} = W_{chair} + W_{student}$

Let's analyze the forces on the student.

$N_{student} - W_{student} = 0 \\N_{student} = W _{student}$

In conclusion using the equilibrium condition we can find the result for the force that the chair exerts on the student is:

The reaction force that the chair exerts on the student's support is equal to the student's weight.

If a shuttle is orbiting a planet at a distance of 40 miles from the center of the planet, and is traveling at a rate of 500 mil

lawyer [7]

Answer:

Time taken, t = 30.15 minutes

Explanation:

It is given that,

Distance from the center of planet, r = 40 miles

Speed of the shuttle, v = 500 miles per hour

Let t is the time taken by it to complete one full orbit. The displacement of the shuttle is,

$d=2\pi r$

$d=2\pi \times 40$

d = 251.32 miles

Now time can be calculated using the expression for the velocity as :

$v=\dfrac{d}{t}$

$t=\dfrac{d}{v}$

$t=\dfrac{251.32\ miles}{500\ miles\ per\ hour}$

t = 0.50264 hours

t = 30.15 minutes

So, the shuttle will take 30.15 minutes to complete one full orbit. Hence, this is the required solution.
