The magnitude of the horizontal component of the crate’s velocity just before it strikes the ground is 100 meters per seconds.

<u>Given the following data:</u>

  • Velocity = 100 m/s
  • Time = 30.0 seconds.

To determine the magnitude of the horizontal component of the crate’s velocity just before it strikes the ground:

<h3>The horizontal component of velocity.</h3>

In Projectile motion, the horizontal component of the velocity represents the influence of velocity in displacing an object (projectile) in the horizontal direction.

Mathematically, the horizontal component of velocity is given by the formula:

V_x = Vcos(\theta)

In this scenario, there isn't any acceleration in the horizontal direction and as such the net force in this horizontal direction is equal to zero (0) in accordance with Newton's Second Law of Motion.

In conclusion, the plane would experience a constant velocity of 100 m/s.

Which of the following is a direct result of the division of powers in federalism
yarga [219]

One effect of the division of powers in federalism is that of segregated schools.

<h3>What happened as a result of federalism?</h3><h3 />

Segregation in schools was done at the state level by Southern states who did not want Whites and African Americans associating.

This happened because federalism allowed states to establish their own schools and laws on governing them.

If a fair coin is tossed 6 times, what is the probability, to the nearest thousandth, of getting exactly 4 heads?
nikitadnepr [17]

Probability of getting exactly 1 heads is 0.094.

As a binomial model, there are only two outcomes, the heads & tails

For a coin, the probability of getting heads or tails = 1 /2 = 0.5

Let 'X' be the no of heads obtained

Let :p" be the probability of getting heads

X~Bin (n=6, p = 0.5)

P (X=x) =  

P (X=x) =  

P (X=x) =  

Note that we need to find probability of getting exactly 1 heads. So we will input the figures

P (X=1) =  

P (X=1) =  

P (X=1) =  

P (X=1) = 0.09375

P (X=1) = 0.094

Therefore, the probability of getting exactly 1 heads is 0.094.
