Answer:
When we double the angular velocity the maximum acceleration
will changes by a factor of 4.
Explanation:
Given the angular frequency
of the simple harmonic oscillator is doubled.
We need to find the change in the maximum acceleration of the oscillator.

Now, according to the problem, the angular frequency
got doubled.
Let us plug
. Then the maximum acceleration will be 



We can see, when we double the angular velocity the maximum acceleration will changes by a factor of 4.
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.
