Answer:
23.4 cm
Explanation:
15 : 50 = x : 78
15*78 = 50x
x = 15*78/50 = 23.4 cm
The spring stretch is, 23.4 cm.
What is the stretch of the spring?
- Potential energy that is stored as a result of the deformation of an elastic item, such as the stretching of a spring, is known as elastic potential energy.
- It is equivalent to the work required to stretch the spring, which depends on both the length of the stretch and the spring constant, k.
What happens to a spring when you stretch it?
- A spring exerts a force F = -kx in the direction of its equilibrium position when it is stretched or compressed to a length that differs by an amount x from its equilibrium length.
- A spring's force acts to return the spring to its equilibrium length; it is a restoring force.
What causes a spring to stretch?
- A typical spring is a tightly wrapped metal coil or spiral that stretches when pulled (by applying force) and returns to its original shape when released (remove the force).
- A spring is elastic, in other words.
According to the question:
15 : 50 = x : 78.
15×78 = 50x.
x = 15×78/50.
= 23.4 cm.
