Spring example problem

This video tutorial explains how to determine the total length of a spring with a 3 kg bucket of water hanging from it. It covers the properties of the spring, such as stiffness and unstretched length, and uses a free body diagram to identify forces acting on the bucket. By applying Newton's laws, the tutorial calculates the stretch of the spring and ultimately finds the total length when the bucket is attached.

What is the mass of the bucket of water hanging from the spring?

• 2 kg

• 3 kg

• 4 kg

• 5 kg

What is the spring stiffness given in the problem?

• 30 N/m

• 60 N/m

• 40 N/m

• 50 N/m

What is the unstretched length of the spring?

• 30 cm

• 20 cm

• 35 cm

• 25 cm

Which law is used to determine the forces acting on the bucket?

• Newton's Third Law

• Newton's Second Law

• Newton's First Law

• Hooke's Law

What is the formula for the force due to gravity on the bucket?

• m / g

• m + g

• m - g

• m * g

How is the total length of the spring calculated?

• L = L₀ + X

• L = L₀ - X

• L = L₀ / X

• L = L₀ * X

What is the final calculated length of the spring with the bucket?

• 0.94 meters

• 1.04 meters

• 1.14 meters

• 1.24 meters
