Calculate the spring constant if the mass is 55g and the extension is 2m​

0.2695 N/m

Explanation:

Applying,

F = ke Equation 1

Where F = Force on the spring, k = spring constant, e = extension.

make k the subject of the equation

k = F/e Equation 2

But,

F = mg Equation 3

Where m = mass, g = acceleration due to gravity

Substitute equation 3 into equation 2

k = mg/e Equation 4

From the question,

Given: m = 55 g = 0.055 kg, e = 2 m

Constant: g = 9.8 m/s²

Substitute these values into equation 4

k = (0.055×9.8)/2

k = 0.2695 N/m

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

it would be kevlar ^^
