Question

A model rocket has a mass of 0.2 kg. A second model rocket is being built with the same motor as the first, but it is being designed to accelerate half as much as the first rocket. What kind of change can be made in the design to achieve this?
Responses

1) The mass of the second rocket should be 0.2 kg
2) The mass of the second rocket should be 0.4 kg.
3) The mass of the second rocket should be 0.1 kg.
4) The mass of the second rocket should be 0.01 kg.

Answer 1

To achieve half the acceleration of the first rocket, option 1 would be the correct response. The mass of the second rocket should be 0.2 kg, the same as the first rocket.
