Question

Force Diagrams 1. If two people try to lift a 400kg stone table off of the ground, one pulling straight up with a force of 1000N and the other pulling it at an angle of 60° from the ground with a force of 1200N will they be able to lift the table? What is the normal force of the floor on the table? What will be the acceleration of the table? 2. As you know monkeys swing between trees holding onto vines. If a monkey is holding one vine at an angle of45 behind her and the other at 45° in front of her and the vines balance her mass of 45kg, what is the force she must apply to each vine? 3. If a package of mass 75kg is on an surface tilted at 20° to the ground and it has a rope attached to it which pulls with a force of 400N directly up, what is the normal force on the package? What is the acceleration of the package?

    1) Tyrion is pulling a 30 kg sled loaded with ale across an ice lake. Assume the sled starts from rest and that it moves a distance of 10 m to the right. He pulls the sled to the right with a force of 300 N at angle of 30° above the horizontal. Once again, Cersei is trying to stop Tyrion from leaving and pulls on the sled horizontally to the left with a force of 100 N. Find the...
