Suppose a skydiver (mass = 75kg) is falling toward the Earth. When the skydiver is 100m above the earth he is moving 60m/s. At t

Answer:

Kinetic energy = 135 kJ

Potential energy = 73.5 kJ

Explanation:

Mass of sky diver = 75 kg

Velocity = 60 m/s

Height = 100 m

Kinetic energy is given by the expression, $KE = \frac{1}{2} mv^2$ , where m is the mass and v is the velocity.

So Kinetic energy = $\frac{1}{2} *75*60^2=135000J=135kJ$

Potential energy is given by the expression, PE =mgh, m is the mass, g is the acceleration due to gravity value and h is the height.

So, Potential energy = 75*9.8*100 = 73500J = 73.5 kJ

Please help me with this math problem.

evablogger [386]

Answer:

The answer is 19.

Step-by-step explanation:

Given that these lines are parallel, these two angles together equal 180.

6x +4 + 4x -14 = 180

-4 +14 +10

6x + 4x = 190

10x = 190

x = 19

Bruce is going to call one person from his contacts at random. He has 25 total contacts. 20 of those contacts are from his neigh

Naya [18.7K]

<h3>P(call a person not from his neighborhood) = $(\frac{1}{5} )$ </h3>

Step-by-step explanation:

Here, the total number of contacts in the list if Bruce = 25 contacts

The total number of neighbors in the contact = 20 people

Now, let E: Event of calling a person from his neighborhood

So, P(E) = $\frac{\textrm{Total Favorable Outcomes}}{\textrm{Total Outcomes}} = \frac{20}{25} = (\frac{4}{5})$

So, the probability of calling a person from his neighborhood is $(\frac{4}{5} )$

⇒P(E) = $(\frac{4}{5} )$

Now,as we know: P(E) + P(not E) = 1

So, the probability of NOT calling a person from neighborhood

= 1 - probability of calling a person from his neighborhood

$= 1 - (\frac{4}{5}) = \frac{5-4}{5} = (\frac{1}{5})$

⇒P( not E) = $(\frac{1}{5} )$

Hence, P(call a person not from his neighborhood) = $(\frac{1}{5} )$
