To solve this problem we will apply Newton's second law, which indicates that the force is equivalent to the product between mass and acceleration, so

Here,
F= Force
m = Mass
a = Acceleration
Rearranging to find the mass we have,

The value of the acceleration is


Replacing to find the mass,



Now in ponds this value is


Therefore the mass of the spacecraft is 52.8lb
The correct answer is - Positive acceleration describes an increase in speed; negative acceleration describes a decrease in speed.
A nuclear particle with no charge is a neutron
False. Bases are substances that dissociate(break down) to give off hydroxide ions in aqueous solutions. The hydroxide ions are what makes them basic.
10,000 units of momentum.
p=mv
20,000=m(2v)
10,000=mv
