Question

Part A Constants | Periodic Table The California sea lion is capable of making extremely fast, tight turns while swimming underwater. In one study, scientists observed a sea lion making a circular turn with a radius of 0.31 m while swimming at 4.4 m/s. What is the sea lion's centripetal acceleration, in units of g? Express your answer in units of 9. ×g Submit Request Answer PartB What percentage is this acceleration of that of an F-15 fighter jet's maximum centripetal acceleration of 9g? Express your answer as a percentage

Answer 1

R = 0.31 m V = 4.4 m/s (A) a_c = V^2/R g = 9.81 m/s^2 = (4.4)^2/0.31 = 62.451 m/s^2 a_c = 62.451/9.81 g = (6.366) times g (B) = 6.366 g/9 g times 100 = 0.7073 times 100 = 70.73 %
