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? (1 point)

Question

Responses

The mass of the second rocket should be 0.2 kg
The mass of the second rocket should be 0.2 kg

The mass of the second rocket should be 0.4 kg.
The mass of the second rocket should be 0.4 kg.

The mass of the second rocket should be 0.1 kg.
The mass of the second rocket should be 0.1 kg.

The mass of the second rocket should be 0.01 kg.

Answer 1

To accelerate half as much with the same motor, you can achieve this by increasing the mass of the second rocket. According to Newton's second law (F = ma), if the force produced by the motor remains the same but you want to achieve half the acceleration, you would need to double the mass of the rocket.

The first rocket has a mass of 0.2 kg, so to achieve half the acceleration, the mass of the second rocket should be:

0.2 kg * 2 = 0.4 kg.

Therefore, the correct response is:

The mass of the second rocket should be 0.4 kg.
