A rocket with a mass of 345 kg is launched vertically. the engine produces a thrust of 17000 N. Neglect air resistance.
a. How would I determine the weight of the rocket?
b. What is the net force being applied to the rocket?
a. weigh= mg
b. net force=thrust-weight
To determine the weight of the rocket, you need to use the formula weight = mass x acceleration due to gravity. The acceleration due to gravity on Earth is approximately 9.8 m/s^2.
a. Use the formula weight = mass x acceleration due to gravity:
weight = 345 kg x 9.8 m/s^2
weight = 3381 N
Therefore, the weight of the rocket is 3381 N.
b. To calculate the net force being applied to the rocket, you need to subtract the weight from the thrust. Since the rocket is launched vertically, the weight acts downwards (opposite to the thrust).
net force = thrust - weight
net force = 17000 N - 3381 N
net force = 13619 N
Hence, the net force being applied to the rocket is 13619 N.
