Tsunami and under water volcano
The answer would be 27,000 Joules because (1/2) m v^2 =30*900 which equals 27,000 J
Potential energy which is the stored energy an object has waiting to be used
Answer:
Use Fc centripetal force as positive and W the weight as negative
N = m v^2 / R + m g
v^2 = (N - m g) R / m
v^2 = (995 - 57 * 9.8) 42.7 / 57 = 327 m^2/s^2
v = 18.1 m/s
Note: N - m g is the net force producing the centripetal force
