Hector is walking his dog (Fido) around the neighborhood. Upon arriving at Fidella's house (a friend of Fido's), Fido turns part mule and refuses to continue on the walk. Hector yanks on the chain with a 67.0 N force at an angle of 30.0° above the horizontal. Determine the horizontal and vertical components of the tension force.
Fx: 58.0 N
Fy: 33.5 N

3. a. Determine the resultant or net force acting upon the carcass.
A pack of three Artic wolves are fighting over the carcass of a dead polar bear. A top view of the magnitude and direction of the three forces is shown in the diagram to the right.
a. Determine the resultant or net force acting upon the carcass.
b. Determine the acceleration of the 750-kg polar bear carcass.
a. 190 N at 23° south of east (or 337°)
b m/s/s

4. Fapp = 67.0 N at 30.0° above the horizontal (rightward and upward)
At one moment during a walk around the block, there are four forces exerted upon Fido - a 10.0 kg dog. The forces are:
Fapp = 67.0 N at 30.0° above the horizontal (rightward and upward)
Fnorm = 64.5 N, up
Ffrict = 27.6 N, left
Fgrav = 98 N, down
Resolve the applied force (Fapp) into horizontal and vertical components, then add the forces up as vectors to determine the net force.
Fapp-horizontal: N, right
Fapp-vertical: 33.5 N, up
Fnet: N, right
