Question

In Space, an astronaut releases a wrench from his hand. The wrench has a mass of 4 grams and is traveling with a velocity of -15m/s. The Astronaut’s mass is 70kg. What is his Velocity?

Answer 1

Answer: -8.5 × 10^-4 m/s

Explanation:

The following can be deduced from the question:

m₁ = Mass of a wrench = 4 g = 0.004 kg

v₁ =Speed of wrench = -15 m/s

m₂ = Mass of the Astronaut = 70 kg

The velocity will be calculated as:

m₁v₁ = m₂v₂

v₂ = [0.004 × (-15)] / 70

= -8.5 × 10^-4 m/s

Therefore, the velocity is -8.5 × 10^-4 m/s
