Three people pull simultaneously on a stubborn donkey. Jack pulls directly ahead of the donkey with a force of 98.1 N, Jill pulls with 90.7 N in a direction 45° to the left, and Jane pulls in a direction 45° to the right with 115 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. magnitude of the net force: What is the direction of the net force? Express this as the angle from straight ahead between 0° and 90°, with a positive sign for angles to the left and a negative sign for angles to the right. direction of the net force:

You have gone skiing at the Poconos. You (mass 45 Kg) are being pulled up a 300 snow-covered slope by a tow rope at constant speed 0.5 m/s. Ignore friction. Calculate the normal force on you and the tension in the rope. (Hint: Draw a force diagram, i.e., all the forces acting on you.) a) Normal force = 382 N, Tension = 220.5 N b) Normal force = 220.5 N, Tension = 382 N
An SUV containing 5 passengers has a mass of 3500 kg. It has a driving force of 2500 N directed west on a perfectly horizontal road. The surface of the road exerts a resistive force of 500 N due east. At the same time, a strong wind is blowing a force of 500 N due east in the opposite direction of the car's drive force. Does the car have any acceleration? If yes, then what is the magnitude and direction of the car's acceleration?
The figure below shows a bird feeder that weighs 189.7 N. The feeder is supported by a vertical string, which is in turn tied to two strings, each of which is attached to a horizontal branch. The left string makes a 60° angle with the branch, while the right string makes a 30° angle. What is the tension in each string (in N)? left string right string bottom string 60° Bird food 30° N N
Two people play tug of war. The 100-kg person on the left pulls with 1100 N, and the 75-kg person on the right pulls with 870 N. Assume that neither person releases their grip on the rope with either hand at any time, assume that the rope is always taut, and assume that the rope does not stretch. What is the magnitude of the tension in the rope in Newtons? Add your answer
Two forces are acting on a 0.150 kg hockey puck as it slides along the ice. The first force has a magnitude of 0.320 N and points 35.0° north of east. The second force has a magnitude of 0.520 N and points 65.0° north of east. If these are the only two forces acting on the puck, what will be the magnitude and direction of the puck's acceleration? Enter the direction as an angle measured in degrees counterclockwise from due east. magnitude of acceleration: m/s2 direction of acceleration: °
