Answer:
2.5m/s²
Force = mass x acceleration
Explanation:
Given parameters
Mass = 200kg
Force = 500N
Unknown:
Acceleration = ?
Solution:
According to the Newton's second law of motion "the constant force applied on a massive body causes it to accelerate".
Mathematically;
Force = mass x acceleration
Now insert the parameters and solve;
Acceleration = 
Acceleration = 
= 2.5m/s²
More force to accelerate. If you push a car compared to a beach ball, which will you have to push harder for it to move? That's pretty much what the question is asking, if that helps any:)

Answer: K =24 psi
Explanation:
Given: Standard deviation =3psi
Internal pressure strength =157psi
Number of random bottle =n=64
K= 3 × square root of 64
K= 3×8=24 psi
If mean internal pressure K fall below K,
157-1.3=155.7psi
At 2%:
0.16×64 = 10.24
