Question

which has more KE ? a 2 g bee flying at 1 m/s OR a 1 g wasp flying at 2 m/s ty! ~​

Answer 1

Answer: Wasp has greater kinetic energy of 0.002 Joules

Given for bee:

• mass: 2g = 2 × 10⁻³ kg

• velocity: 1 m/s

Given for wasp:

• mass: 1 g = 1 × 10⁻³ kg

• velocity: 2 m/s

Formula:

• Kinetic Energy (J) = ½ × mass (kg) × velocity² (m/s)

Kinetic energy of bee:

• ½ × 2 × 10⁻³ × 1² = 1 × 10⁻³ Joules ≈ 0.001 Joules

Kinetic energy of wasp:

• ½ × 1 × 10⁻³ × 2² = 2 × 10⁻³ Joules ≈ 0.002 Joules

From this, it is determined wasp has greater kinetic energy.
