DATA The electric potential in a region that is within 2.00 m of the origin of a rectangular coordinate system is given by V = Ax i + By m + Cz n + D , where A , B , C , D , l , m , and n are constants. The units of A , B , C , and D are such that if x , y , and z are in meters, then V is in volts. You measure V and each component of the electric field at four points and obtain these results: (a) Use the data in the table to calculate A , B , C , D , l , m , and n . (b) What are V and the magnitude of E at the points (0, 0, 0), (0.50 m, 0.50 m. 0.50 m), and (1.00 m, 1.00 m, 1.00 m)?

The determined Wile E. Coyote is out once more to try to capture the elusive Road Runner of Loony Tunes fame. The coyote is strapped to a rocket, which provide a constant horizontal acceleration of 15.0 m/s2. The coyote starts off at rest 79.2 m from the edge of a cliff at the instant the roadrunner zips by in the direction of the cliff. If the roadrunner moves with constant speed, find the minimum velocity the roadrunner must have to reach the cliff before the coyote. (proper sig fig)
Hello, I need some help with calculations for a lab, it is Kinematics: Finding Acceleration Due to Gravity. Equations: s=s0+v0t+1/2at2 and a=gsinθ. The hypotenuse,r, is 100cm (given) and a height, y, is 3.5 cm (given). How do I find the Angle θ1? And, for distance traveled, s, would all be 100cm? For my first observations I recorded four trials in seconds: 1 - 2.13s, 2 - 2.60s, 3 - 2.08s, & 4 - 1.95s. This would all go in the coloumn for time right? How do I solve for the experimental approximation of the acceleration? Help with trial 1 would be great so I can use that as a model for the other trials. Thanks!
