Awoman is going to a friends house to discuss opening a business. at 11am she starts from rest and accelerates at a constant 2.5m/s2 for 9s to get to cruising speed. she drives for 15 minutes at this constant speed before she enters city traffic. she stops at her friends house which is straight lined from hers 27km. she arrives at 12: 15. time interval is 11 to 12: 15.
what is her initial velocity? what is her final velocity? what is her average velocity? what is her velocity 9s into the trip?

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.

Veronica’s velocity was measured as 4.3 m/s. she displaced 20 meters in 4.7 seconds. which piece of information is missing for the correct calculation of velocity? the starting point the direction the end point the time per meter
