Answer:
A. We know that amplitude at x is
Asin (kx)
But k= 2πf/v
k= 2*3.132*235/193= 7.65
So A = 0.35*sin( 7.65x 0.18)= 0.00841m
C
Vmax = Amplitude x angular velocity
= 0.0084 x 2πf
= 0.0084* 2*3.142* 235= 12.4m/s
D. Maximum acceleration = omega² x Amplitude
= (2πf)²* 0.00841= 183.40m/s²
Imma go with A.
Hope this helps:)
Answer:
1.48 m/s
Explanation:
If it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, then the period for the boat to travel from its highest point back to its highest point again is twice that, which is 2.2 * 2 = 4.4 s
Since wave crests are spaced a horizontal distance of 6.50 m apart, we can calculate the speed that waves are traveling at
6.5 / 4.4 = 1.48 m/s
