UNIT V: Worksheet 1
An elevator is moving up at a constant velocity of 2.5 m/s, as illustrated in the diagram below: The
man has a mass of 85. kg.
Construct a force diagram for the man.
What force does the floor exert on the man?
For each of the problems below, you must begin your solution with a force diagram. Some
require more than one diagram.
1. A 4600 kg helicopter accelerates upward at 2.0 m/s 2. What lift force is exerted by the air on

For each of the problems below, carefully draw a force diagram of the system before attempting
to solve the problem.
1. Determine the tension in each cable in case A and case B.
In each of the following situations, represent the object with a particle. Sketch all the forces acting
upon the object, making the length of each vector represent the magnitude of the force.
