Question

A 16.7kg dog is running northward at 2.21m/s , while a 4.48kg cat is running eastward at 3.00m/s . Their 77.8kg owner has the same momentum as the two pets taken together. Part A Find the direction and magnitude of the owner's velocity. ANSWER:   ? =   ? north of east Part B ANSWER:   v =   m/s   A 16.7kg dog is running northward at 2.21m/s , while a 4.48kg cat is running eastward at 3.00m/s .

Explanation / Answer

(16.7*2.21)j+(4.48*3.0)i=77.8(v3)

0.47j+.172i=v3=0.50m/s at 69.8 north of east
