A ring is attached at the center of the underside of a trampoline. A sneaky teenager crawls under the trampoline and uses the ri

Karo-lina-s [1.5K]

Answer:

Explanation:

Given

Mass of mother $m=79\ kg$

Mother is released with a speed of $v=2.5\ m/s$

Assuming we need to find elastic Potential energy stored in Trampoline

Kinetic energy acquired by Mother comes from Elastic Potential Energy stored in the spring

I.e. Elastic Potential Energy=Kinetic Energy of mother

$\frac{1}{2}kx^2=\frac{1}{2}mv^2$

$E=\frac{1}{2}\times 79\times 2.5^2=246.875\ J$

So 246.875 J of Energy is stored in the trampoline as he pull the ring

jeyben [28]

Answer:

s = 90 m

a = 56 m/s²

Explanation:

I will ASSUME that your equation is silly as it reduces to V = 11t which is constant, and that you mean V = 9t² + 2t

Position is the integral of differential velocities

s = $\int\limits^3_0 {9t^2 + 2t} \, dt$

s = 3t³ + t² | from 0 to 3

s = 3(3)³ + 3² - (0) = 90 m

acceleration is the derivative of velocity

a = v' = 18t + 2

a(3) = 18(3) + 2 = 56 m/s²

6. To show how powerful he is, Mr. Avalos pushes on the wall with a force of 150 N for a whole minute!

If the wall doesn't move, its mean that <u>the work he did is 0 J</u>.

<h3>Introduction</h3>

Hello my friend ! Here, I will help you. Alright, before it, I will to introduce to you about work (physics). In the world of physics, <u>work is the amount of force exerted to cause an object to move a certain distance from its starting point</u>. The amount of work will be proportional to the increase in force and increase in displacement. Amount of work can be calculated by this equation :

$\boxed{\sf{\bold{W = F \times s}}}$
