14.484 kilometers
Explanation:
formula= for an approximate result, multiply the length value by 1.609
<span>Molecular mass of C is: 12.01 g/mol
1 mole C: 0.012 kg
Molecular mass of H is: 1.08 g/mol
1 mole H: 0.01 kg
Reduced mass: Mr = m1m2/(m1+m2) = 0.012*0.01/(0.022) = 5.45x10-³ kg
f = (1/2π)√(k/Mr) = (1/2π)√{500/5.45x10-³} = (1/2π)10²√{9.166} = 48.1 Hz. I hope this helps </span>

Explanation:
All you gotta do is think about it for a minute
Answer:
a) V_f = 25.514 m/s
b) Q =53.46 degrees CCW from + x-axis
Explanation:
Given:
- Initial speed V_i = 20.5 j m/s
- Acceleration a = 0.31 i m/s^2
- Time duration for acceleration t = 49.0 s
Find:
(a) What is the magnitude of the satellite's velocity when the thruster turns off?
(b) What is the direction of the satellite's velocity when the thruster turns off? Give your answer as an angle measured counterclockwise from the +x-axis.
Solution:
- We can apply the kinematic equation of motion for our problem assuming a constant acceleration as given:
V_f = V_i + a*t
V_f = 20.5 j + 0.31 i *49
V_f = 20.5 j + 15.19 i
- The magnitude of the velocity vector is given by:
V_f = sqrt ( 20.5^2 + 15.19^2)
V_f = sqrt(650.9861)
V_f = 25.514 m/s
- The direction of the velocity vector can be computed by using x and y components of velocity found above:
tan(Q) = (V_y / V_x)
Q = arctan (20.5 / 15.19)
Q =53.46 degrees
- The velocity vector is at angle @ 53.46 degrees CCW from the positive x-axis.
Answer: D
Explanation: The kinetic energy would become Zero.
According to conservative of energy, the total energy is equal to maximum K.E plus maximum P.E.
As the object comes to rest the potential energy will be maximum, and Kinetic energy becomes zero.
