5. A mountain climbing expedition establishes a base camp and two intermediate camps, A and B. Camp A is 11,900 m east of and 3,400 m above base camp Camp B is 8,500 m east of and 1,700 m higher than
Camp A. Determine the displacement between base camp and Camp B. (Use 1 cm = 1700 m)

1. explain how you calculate the net force in any direction on the box. 2. suppose an upward force of 15n is added to the box. what will be the net vertical force on the box? 3. what force could be applied to the box to make the net force in the horizontal direction zero? explain. 4. suppose a force of 25n to the right is added to the box. what will be the net force to the right?
