A 0.142 kg remote control 24.0 cm long rests on a table, as shown in the figure (Figure 1), with a length L overhanging its edge. To operate the power button on this remote requires a force of 0.355 N.

Hink about the friction activity. Return to this activity to see it again if you need to. Explain what happened in each of the two demonstrations, and then compare them. Use the terms resistance, vacuum, gravity, velocity, and friction.
