Sagot :
Question 1.
To find the weight of the rocket, we will just simply multiply its mass by g, which is 9.8 m/s^2.
1400 kg * 9.8 m/s^2 = 13720 kg * m/s^2
The weight of the rocket is 13720 N
Question 2.
To find the acceleration of the rocket upon launch, we will be using the formula F = ma.
F = ma
a = F / m
a = 30000 kg*m/s^2 / 1400 kg
a = 21.43 m/s^2
The acceleration of the rocket upon launch is 21.43 m/s^2
