The launch velocity is at 41.1° relative to the horizontal.
Let V = the launch velocity, ft/s
The horizontal component of the velocity is
Vx =Vcos(41.1°) = 0.7536V ft/s
The vertical component of the launch velocity is
Vy = Vsin(41.1) = 0.6574V ft/s

Assume that g = 32 ft/s² and neglect air resistance. 

At the maximum height of 11.7 ft, the vertical velocity is zero. Therefore
Vy² - 2*32*11.7 = 0
Vy² = 748.8
Vy = 27.3642 ft/s

Therefore
0.6574V = 27.3642
V = 41.8285 ft/s

Note that
1 ft/s = 0.3048 m/s
Therefore
V = 41.8285*0.3048 = 12.749 m/s

Answer: 12.75 m/s

On a recent adventure trip, Anita Break went rock-climbing. Anita was able to steadily lift her 800- kg body 20.0 meters in 100
Irina-Kira [14]

Answer:

Anita 's power rating during this portion of the climb is 1568 Watts.

Explanation:

Given that,

Mass of the body, m = 800 kg

Height, h = 20 m

Time, t = 100 s

We need to find the Anita 's power rating during this portion of the climb. Power rating of an object is given by the work done per unit time. It is given by :

P=\dfrac{W}{t}

P=\dfrac{mgh}{t}

P=\dfrac{800\times 9.8\times 20}{100}

P = 1568 Watts

So, Anita 's power rating during this portion of the climb is 1568 Watts. Hence, this is the required solution.

A sample of a substance has a high density, yet a low particle motion. This sample must be a
avanturin [10]
The most possible answer is letter B) Liquid. 
If we are going to base the answer to the motion of particles, liquid is the best answer since solid's particle cannot move for they are tightly packed while the particles of gas and plasma (ionized gas) are free and move at high speeds.

A 40kg skier starts at the top of a 12 meter high slope at the bottom she is traveling g 10m/a how much energy does she lose to
nikdorinn [45]
Energy at top = U = mgh = 40 * 9.8 * 12 = 4704 J

Energy at bottom = 1/2 mv² = 1/2 * 40 * 10² = 4000 / 2 = 2000 J

Energy Lost = Final - Initial = 4704 - 2000 = 2704 J

In short, Your Answer would be 2704 Joules

Hope this helps!
