When stretched by L / 20:
Speed = v
When stretched by L / 10:
Speed =?
By cross multiplication we can get this speed.
L / 20 = v
L / 10 =?
L / 10 × 20 / L × v = 2v
Speed = 2v
Speed = v
When stretched by L / 10:
Speed =?
By cross multiplication we can get this speed.
L / 20 = v
L / 10 =?
L / 10 × 20 / L × v = 2v
Speed = 2v
