Three very large sheets are separated by equal distances of 15.0 cm (Fig. 22–47). The first and third sheets are very thin and nonconducting and have charge per unit area σ of +5.00 μ C/m 2 and −5.00 μ C/m 2 respectively. The middle sheet is conducting but has no net charge. ( a ) What is the electric field inside the middle sheet? What is the electric field ( b ) between the left and middle sheets, and ( c ) between the middle and right sheets? ( d ) What is the charge density on the surface of the middle sheet facing the left sheet, and ( e ) on the surface facing the right sheet? FIGURE 22–47 Problem 63.

Race car driver is cruising down the street at a constant speed of 28.9 m/s (~65 mph; he has a “lead” foot) when the traffic light in front of him turns red. a) If the driver’s reaction time is 160 ms, how far does he and his car travel down the road from the instant he sees the light change to the instant he begins to slow down? b) If the driver’s combined reaction and movement time is 750 ms, how far do he and his car travel down the road from the instant he sees the light change to the instant he slams on her brakes and car begins to slow down? Please answer parts a-B. Show all work. For each question draw a diagram to show the vector/s. Show all the step and provide units in the answers. Provide answer to 2 decimal places. DONT FORGET TO DRAW VECTORS! ONLY USE BASIC FORMULAS TAUGHT IN PHYSICS. distance = speed * time.

Please answer parts a-c. Show all work. For each question draw a diagram to show the vector/s. Show all the step and provide units in the answers.
