Question

Cookie, the guinea pig, is exploring the yard. He begins at a positions of -3mx(hat) -5my(hat) in the given refrence frame. Cookie then travels 3my(hat) away from the position where he finds a carrot. From there, he runs to his cage at the origin of this refrence frame.

Please show all work with explanation, Thank you!

A. What is his position at the carrot ain the given refrence frame?

B. What is his velocity (assuming it is constant) fromt he cage to the carrot if it takes him 10s to run from the cage to the carrot?

Explanation / Answer

As

xi = (-3i - 5j) meter

dx = 3j meter

So xf = xi + dx = (-3i - 2j) meter

So for

A

xf = xi + dx = (-3i - 2j) meter

B

v = dx/10 = 0.3j m/s
