Answer:
Mass = 2154 grams
Step-by-step explanation:
Given the following data;
Acceleration = 520m/s²
Force = 11.2N
To find the mass;
Force = mass * acceleration
Mass = force/acceleration
Substituting into the equation, we have;
Mass = 11.2/520
Mass = 2.154 kg
Therefore, the value of mass in grams;
1000 grams = 1 kilograms
x grams = 2.154 kilograms
Cross-multiplying, we have;
2.154 * 1000 = 2154 grams.
Mass = 2154 grams.
Therefore, the mass of the model rocket is equal to 2154 grams.
