Determine the launch speed of a horizontally launched projectile that lands 26.3m from the base of a 19.3m high cliff

Physics

mote1985 [20]2 years ago
5 0

The launch speed of a horizontally launched projectile is 13.28 m/s.

<h3>Time of motion of the projectile</h3>

The time of motion is calculated as follows;

t = √(2h / g)

where;

  • h is height of the cliff
  • g is acceleration due to gravity

t = √(2 x 19.3 / 9.8)

t = 1.98 s

<h3>Launch speed of the projectile</h3>

X = Vxt

Vx = X/t

Vx = (26.3)/(1.98)

Vx = 13.28 m/s

Thus, the launch speed of a horizontally launched projectile is 13.28 m/s.

What value of x is in the solution set of 2(3x – 1) ≥ 4x – 6?
Akimi4 [234]
2(3x - 1) ≥ 4x - 6  Remove the brackets on the left.
6x - 2  ≥ 4x - 6     Subtract 4x from both sides.
6x - 4x - 2 ≥ - 6    combine like terms on the left.
2x - 2 ≥ - 6           Add 2 to both sides
2x ≥ - 6+ 2
2x ≥ -4                 Divide by 2
x ≥ - 4/2
x ≥ - 2  answer <<<<<<<<

Check
2(3*-2 - 1) ≥ 4x - 6
2(-6 - 1) ≥ 4(-2) - 6
2(-7) ≥- 8 - 6
- 14 = - 14 and this checks.

True or false:<br> All of the rivers in the United States are closely monitored For pollution levels
Nutka1998 [239]

All of the rivers in the United States are not monitored closely for pollution levels.

The statement in the question is False

<h3><u>Explanation:</u></h3>

Not all rivers in the United States are closely monitored for their pollution levels. There are volunteers who take responsibility of checking water bodies such as lakes, rivers, streams etc. They take the next step required after finding a water body contaminated.

But to say that all the rivers receive the same amount of attention and action is incorrect. To ensure that all the rivers are clean and pollution free, it would require a lot of man power in the said department which would collect the water samples from all these rivers and send it to labs for checking the pollution level of the particular river. It can be said that the rivers which are situated beside an industrial site, close to a town, will be the priority for checking pollution levels as it would directly cause harm to a small set of population if the toxicity is at an increased level.
