The force required to stretch a spring by 1 m from its unstretched length is 150 N. What is the force required to stretch the sp
ring by 3 m? 450 N
200 N
600 N
300 N
1 answer:
Answer:
450 N.
Step-by-step explanation:
By Hooke's law
Force = k * displacement so
150 = k * 1
So k = 150 and the equation is
F = 150 d
So when d = 3
F = 150 * 3 = 450.
