c) at what times does the cart have an acceleration of zero ?
d) at what times does the cart have the most kinetic energy ?
e) at what times does the cart have the most potential energy ?

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

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

you can cut your hand off if your not

answer is slate

hope this
