1. Over the entrance to a restaurant is mounted a strip of equally spaced light bulbs, as shown in the figure at the side. Starting at the left end, each bulb turns on in sequence for one-half second. Thus, a lighted bulb appears to move from left to right. After the last bulb on the right turns on, the apparent motion reverses. The lighted bulb then appears to move to the left, as part b of the drawing indicates. As a result, the lighted bulb appears to oscillate back and forth. Is the apparent motion simple harmonic motion? Explain.

Question 1a. A soccer goal, found is a city park, is made up of tubing that supports an odd-shaped hanging net behind the goal, but has a rectangular opening infront. The height of the opening is 2.5m and the width is 3.2m. If a uniform E-field, with a magnitude of 0.1N/C, passes through the goal from the front to the back, entering at 90 degrees to the plane of the goal opening, what is the flux through the net? Also, find the flux through the net if the E-fieldenters the goal at 60 degrees angle to the plane of the front goal. In both cases, assume that there no charge found inside the goal itself.

EXERCISE HINTS: GETTING STARTED I I'M STUCK! While standing atop a building 46.4 m tall, you spot a friend standing on a street corner. Using a protractor and a dangling plumb bob, you find that the angle between the horizontal and the direction to the spot on the sidewalk where your friend is standing is 23.2°. Your eyes are located 1.79 m above the top of the building. How far away from the foot of the building is your friend? X
A car is traveling at night along a highway shaped like a parabola with its vertex at the origin. The car starts at a point 100 m west and 100 m north of the origin and travels in an easterly direction. There is a statue located 100 m east and 50 m north of the origin. At what point on the highway will the car’s headlights illuminate the statue?
