Question

**Problem Statement:**

1. The figure shows three forces applied to a trunk that moves leftward by 2.54 m over a frictionless floor.
The force magnitudes are \( F_1 = 5.08 \, \text{N} \), \( F_2 = 8.87 \, \text{N} \), and \( F_3 = 3.39 \, \text{N} \), and the indicated angle is \( \theta = 60^\circ \).

![Diagram](image_url) [Note: Replace with actual image link if available]

**Diagram Explanation:**
- The diagram shows a horizontal surface with a rectangular trunk on it.
- Three forces are acting on the trunk:
- \( \vec{F_1} \) acting to the left.
- \( \vec{F_2} \) acting upwards and at an angle \( \theta = 60^\circ \) to the left of vertical.
- \( \vec{F_3} \) acting downwards at an angle.

**Questions:**

a) During the displacement, what is the net work done on the trunk by the three applied forces, the gravitational force, and the normal force?

b) Is there a net transfer of energy to or from the trunk?

c) Does the kinetic energy of the trunk increase or decrease?

It is not possible to see very small objects, such as viruses, using an ordinary light microscope. An electron microscope can view such objects using an electron beam instead of a light beam. Electron microscopy has proved invaluable for investigations of viruses, cell membranes and subcellular structures, bacterial surfaces, visual receptors, chloroplasts, and the contractile properties of muscles. The "lenses" of an electron microscope consist of electric and magnetic fields that control the electron beam. As an example of the manipulation of an electron beam, consider an electron traveling away from the origin along the x axis in the xy plane with initial velocity v, = vi. As it passes through the region x = 0 to x = d, the electron experiences acceleration a = aî + aj, where a, and a., are constants.
