Answer:
m = 81281.5 pounds.
Explanation:
Given that,
Force, F = 73 kN
Acceleration of the space shuttle, a = 16000 mi/h²
1 miles/h² = 0.0001241 m/s2
16000 mi/h² = 1.98 m/s²
We need to find the mass of the spacecraft.
According to Newton's second law,
F = ma
m is mass of the spacecraft
Since, 1 kg = 2.20462 pounds
m = 81281.5 pounds
Hence, the mass of the spacecraft is 81281.5 pounds.

Alpha particles are composite particles consisting of two protons and two neutrons tightly bound together.
(not much explanation, I hope this is what you were looking for!)
Assuming that what you typed meant 20 seconds, rather than 2o seconds, the car is travelling at a velocity of 200 meters per second.
The SI unit of energy is joule(J). Hope this helps!
