On Jupiter the acceleration due to gravity is 24.8 m/s2. If you start from rest how fast will you be traveling after 1.5 s?

the reason is because the moon has some form of gravity, and that gravity pulls the ocean tides.

there are no correct statementd on the list of choices you provided.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
