A bowling ball is traveling at 3 m/s. It starts to roll up a ramp. How high above the ground will the ball be when it stops roll

ing? Neglect friction and assume the ramp is plenty long enough to do this. (For this problem your initial kinetic energy can be set equal to your final potential energy. 1/2mv2 = mgh).

Answer:

h= 0.45 m

Explanation:

PE= 1/2 mv^2             KE= mgh

v= 3m/s

vf= 0 m/s

h=?

PE= 1/2(1kg)(3m/s)^2

PE= 4.5 J

4.5 J/ 1kg(9.8 m/s^2)

h=0.45 m

Sonbull [250]

Answer:

Consciousness

Explanation:

Obstructionism is the philosophy which dictates that a process needs to be delayed or stopped from occurring.

Transcendence means to achieve a state higher than the previous state.

Hyperkinesis is the condition where a person is unable to concentrate on something and is hyperactive.

Consciousness is the state from which an organism knows their existence and is aware of things that are present externally. Here, Britney is aware of her existence and the existence of other things around her.

Hence, she would be considered to be in a state of Consciousness

A two-dimensional crystal has a rectangular unit cell, with spacings between the centers of the atoms of 0.5 nm in one direction
pav-90 [236]

So directly the cell density value in a rectangle is:

5*10^{17} cells/cm^{2}

In this exercise, we must first calculate the area of ​​the rectangle, remembering that you need to convert from nm to cm is:

A=B*H\\A=(0.4*10^{-7})*(0.5*10^{-7})= 2*10^{-15}

Next, let's calculate the density from the calculated area:

\frac{N}{A} = \frac{1000}{2*10^{-15} } = 5*10^{17}

In this way, the calculation represents that there is:

5*10^{17} cells/cm^{2}

ruslelena [56]

Answer:

<em>The ball will go as high as 8.46 m</em>

Explanation:

<u>Projectile Motion</u>

It's the type of motion that experiences an object launched at a certain height above the ground and moves along a curved path exclusively under the action of gravity.

Being vo the initial speed of the object, θ the initial launch angle, and g the acceleration of gravity, then the maximum height hm can be calculated as follows:

\displaystyle h_m=\frac{v_o^2\cdot \sin^2\theta}{2g}

The soccer ball is kicked at a speed of vo=24 m/s at an angle of θ=31°. Taking the value of g=9.8 m/s^2, then:

\displaystyle h_m=\frac{24^2\cdot \sin^2 31^\circ}{2\cdot 9.8}

\displaystyle h_m=\frac{576\cdot 0.2653}{19.6}

h_m=7.80~m

The ball will go as high as 8.46 m
