Question 23

A space probe has a mass of 2.5 × 104 kg and is travelling at 16 km/s towards a planet.

Which of these is the correct calculation of the momentum of the space probe in kg m/s\text{kg m/s}kg m/s?

Use the equation:

p=m×v p = m \times v p=m×v
A

4.0×105 kg m/s4.0 \times 10^5 \text{ kg m/s}4.0×105 kg m/s

B

4.0×107 kg m/s4.0 \times 10^7 \text{ kg m/s}4.0×107 kg m/s

C

4.0×108 kg m/s4.0 \times 10^8 \text{ kg m/s}4.0×108 kg m/s

D

4.0×1011 kg m/s4.0 \times 10^{11} \text{ kg m/s}4.0×1011 kg m/s
