Answer:
20N
Explanation:
The force (Hooke's Law) is proportional to the deformation. To extend the spring 4 times longer, you will need 4 times the force. In total, 20 N
The amount of work required to stretch the spring 0.4 m give the data is 4 J
How to determine the spring constant
From the question given above, the following data were obtained
- Force (F) = 5 N
- Compression (e) = 0.1 m
- Spring constant (K) =?
K = F/ e
K = 5 / 0.1
K = 50 N/m
How to determine the work
- Spring constant (K) = 50 N/m
- Extention (e) = 0.4 m
- Work =?
W = ½Ke²
W = ½ × 50 × 0.4²
W = 25 × 0.16
W = 4 J
