0.15 m
Explanation:
Time period is
Frequency is
Velocity is given by
The waves are traveling at 1.2 m/s
Amplitude is given by
Amplitude is 0.31 m
If d = 0.3 m
The amplitude would be 0.15 m. The speed would remain the same.
Answer:
F = (913.14 , 274.87 )
|F| = 953.61 direction 16.71°
Explanation:
To calculate the resultant force you take into account both x and y component of the implied forces:
Thus, the net force over the body is:
Next, you calculate the magnitude of the force:
and the direction is:
