A pack of four Arctic wolves are exerting four different forces upon the carcass of a 500 kg deadpolar bear. Wolf one is pulling on the bear with a force of 20 Newtons (N) due north. Wolf twois pulling on the bear with a force of 30 N, 30 degrees north of west. Wolf three is pulling onthe bear with a force of 25 N due west, and wolf four is pulling on the bear with a force of 35 N,10 degrees west of south. Determine the net force acting upon the polar bear and the directionof that force measured north of west. Then compute the magnitude of the acceleration of thepolar bear.

This much information can be scary at first but we are just going to use the techniqueswe have learned above and work our way through. Take a deep breath. You will be fine.Your first step should always be to draw a diagram of the situation. Do so here: (Hint: Drawthis as though you are looking down on it from directly above with the bear at the origin ofyour coordinate system, like a two-dimensional tug-o’-war…
The helicopter view in the figure below shows two people pulling on a stubborn mule. (Take F, = 137 N and F, = 83.0 N.) F F1 75.0° 60.0° (a) Find the single force that is equivalent to the two forces shown. magnitude N direction ° counterclockwise from the +x-axis (b) Find the force a third person would have to exert on the mule to make the net force equal to zero. magnitude N direction ° counterclockwise from the +x-axis
Two bulldozers are pushing against a large pile of dirt. The first bulldozer pushes with a force, F1 = 20.5 kN at an angle of 10.0 degrees East of North. The second bulldozer pushes with a force, F2 = 15.7 kN at an angle of 20 degrees West of North. Friction forces between the pile of dirt and the ground produce a force of 10.7 kN, straight South. Determine the total force, in kiloNewtons, on the pile of dirt. Note that a kN = kiloNewton = 103 N
Three people pull simultaneously on a stubborn donkey. Jack pulls eastward with a force of 94.5 N,94.5 N, Jill pulls with 88.1 N88.1 N in the northeast direction, and Jane pulls to the southeast with 181 N.181 N. (Since the donkey is involved with such uncoordinated people, who can blame it for being stubborn?) Find the magnitude of the net force the people exert on the donkey. What is the direction of the net force? Express this as the angle from the east direction between 0°0° and 90°,90°, with a positive sign for north of east and a negative sign for south of east.

Five boys are pushing on a snowball, and each is pushing with a force of 10.0 N. However, each boy is pushing in a different direction. They are pushing north, northeast, east, southeast, and south. (Each boy is pushing at an angle of 45.0° relative to his neighbor.) What is the magnitude of the total force on the ball?
A crate is pulled to the right with a force of 72.2 N, to the left with a force of 119.2 N, upward with a force of 590.8 N, and downward with a force of 244.2 N. What is the net external force in the y-direction? Answer in units of N. What is the magnitude of the net external force on the crate? Answer in units of N.
A 1000-kg barge is being towed by means of two horizontal cables. One cable is pulling with a force of 80.0 N in a direction 30.0º west of north. The second cable pulls in a direction 20.0º east of north. The magnitude of its pulling force should be 117 N, so that the barge will accelerate northward. true or false?
