Answer: 2

Explanation:

The formula for kinetic energy is given as:

K = (1/2)mv²

Let's denote K as the new kinetic energy and K₀ as the original kinetic energy. Since the kinetic energy is increased by a factor of 4:

K = 4K₀

(1/2)mv² = 4(1/2)mv₀²

Cancel out the common terms:

v² = 4v₀²

Solve for v:

v = 2v₀

Since the new speed is twice the original speed, the speed increases by a factor of 2.
