Homework Statement


"Darryl drives his load of tomatoes 14.0 km [E], 6.0 km [N], 12.0 km [ N 15° E], and then 2.0 km [N 65° E]. This takes him 42 minutes."

Question: Draw a graph representing Darryl's movement

Homework Equations

The Attempt at a Solution


I posted my 'solution' in the thumbnail, I just wanted to know if this was correct or not. I've looked at a few problems similar to this one and I feel like I am getting something wrong, but I can't quite tell.

Looks good.

I really appreciate the verification! I was stressing out over whether I did it correctly or not for a while :p
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
