A Gatorade bottle is dropped on a waterslide. It accelerates at 4.0 m/s2 for 9.0s from rest. What is the slide’s length?

With an acceleration of 4.0 m/s², the bottle attains a speed of

(4.0 m/s²) * (9.0 s) = 36 m/s

so that the slide has length ∆<em>x</em> such that

(36 m/s)² - 0² = 2 * (4.0 m/s²) * ∆<em>x</em>

==>  ∆<em>x</em> = 162 m ≈ 160 m

Alternatively, we know the bottle covers a distance ∆<em>x</em> with acceleration <em>a</em> at time <em>t</em> according to

∆<em>x</em> = 1/2 <em>a</em> <em>t</em>²

so that

∆<em>x</em> = 1/2 * (4.0 m/s²) * (9.0 s)² = 162 m ≈ 160 m

Why is thermal expansion an important consideration for engineering?
Dennis_Churaev [7]

Answer:

Explanation:

Thermal expansion is where materials expand while being heated, causing them to take up more space. Some materials expand more than others. But this all happens due to the motion of tiny little molecules. Temperature is the average kinetic energy of the molecules in a substance.

Thermal expansion is an important consideration for engineering because different materials exhibit changes in size when exposed to heat. Thus, affecting length, width, surface area, volume, shape etc

If the gravitational force between objects of equal mass is 2.30 x 10^‐8 N when the objects are 10.0 m apart, what is the mass o
Readme [11.4K]

Answer:

Mass of each objects, m = 185.69 kg

Explanation:

The gravitational force between two equal masses is, F=2.3\times 10^{-8}\ N

Separation between the masses, d = 10 m

Let m is the mass of each object. The gravitational force is given by :

F=G\dfrac{m^2}{d^2}

m=\sqrt{\dfrac{F.d^2}{G}}

m=\sqrt{\dfrac{2.3\times 10^{-8}\times (10)^2}{6.67\times 10^{-11}}}

m = 185.69 kg

So, the mass of each objects is 185.69 kg. Hence, this is the required solution.

Which type of fitness is not based on performance?
Aneli [31]
Fitness can be measured during the actual performance.
Which means that there are a lot of factors that can affect agility, speed, and coordination beside the physical factors itself. Meanwhile, flexibility solely depends on the physical Factors.


The answer is flexibility .


Hope this helps (:
