Explanation:
x = Compression of the spring
k = Spring constant = 53 N/m
Initial length = 18 cm
P = Kinetic energy
K = Kinetic energy
At the lowest point of the mass the energy conservation is as follows
At its lowest position the mark on the ruler will be
The spring line will end up at 1.07 m
Answer:
Fapp = 3 N
Explanation:
- Applying the work-energy theorem, we know that the net work done on one object by an applied force, is equal to the change in the kinetic energy of the object.
- This work is just the product of the applied force times the displacement, as follows:
- This must be equal to the change in kinetic energy:
- Equating (1) and (2), and replacing by the givens, we can solve for Fapp, as follows:
- The magnitude of the applied force is 3 N.
