a. Determine the spring’s force constant.

The force constant (k) of a spring is given by Hooke's Law, F = kx, where F is the force applied, x is the displacement of the spring, and k is the spring constant. We can rearrange this to solve for k: k = F/x.

Given:
F = 2000N (force applied)
x = 35cm = 0.35m (converted from cm to m)

Substituting these values into the formula, we get:

k = F/x = 2000N / 0.35m = 5714.29 N/m

So, the spring's force constant is 5714.29 N/m.

b. Find the elastic potential energy stored in the spring.

The elastic potential energy (U) stored in a spring is given by the formula U = 0.5*k*x^2, where k is the spring constant and x is the displacement of the spring.

Substituting the given values into the formula, we get:

U = 0.5 * 5714.29 N/m * (0.35m)^2 = 350 Nm = 350 J

So, the elastic potential energy stored in the spring is 350 Joules.

c. If the spring is released, calculate the kinetic energy of the stone when it returns to its original position.

When the spring is released and the mass returns to its original position, all the potential energy stored in the spring is converted into kinetic energy (assuming no energy losses). Therefore, the kinetic energy of the mass is equal to the potential energy stored in the spring.

So, the kinetic energy of the mass is also 350 Joules.

d. Assuming no loss of energy, determine the maximum height that the mass will reach.

When the mass is at its maximum height, all the kinetic energy is converted into gravitational potential energy. The gravitational potential energy (U) is given by the formula U = m*g*h, where m is the mass, g is the acceleration due to gravity (approx. 9.8 m/s^2), and h is the height.

We can rearrange this formula to solve for h: h = U / (m*g).

Substituting the given values into the formula, we get:

h = U / (m*g) = 350 J / (20 kg * 9.8 m/s^2) = 1.79 m

So, the maximum height that the mass will reach is approximately 1.79 meters.
