Initially, the spring stretches by 3 cm under a force of 15 N. From these data, we can find the value of the spring constant, given by Hook's law:
where F is the force applied, and
is the stretch of the spring with respect to its equilibrium position. Using the data, we find
Now a force of 30 N is applied to the same spring, with constant k=5.0 N/cm. Using again Hook's law, we can find the new stretch of the spring:
where F is the force applied, and
Now a force of 30 N is applied to the same spring, with constant k=5.0 N/cm. Using again Hook's law, we can find the new stretch of the spring:
Refer to the diagram shown below.
Let x = distance of the base of the ladder from the base of the hill.
By definition,
sin(75°) = x/15
x = 75*cos(75°) = 3.882 ft
Answer:
The distance between the base of the hill and the base of the ladder is 3.9 ft (nearest tenth)
