Oh no! Your car breaks down on the highway, and you have to push the car to the side of the road. If your car is 400 kg and you push with a force of 200 N, what is the car’s acceleration? A. 8.0 x 104 m/s2
B. 0.5 m/s2
C. 2 m/s2
D. 0 m/s2

Two rigid transformations are used to map δhjk to δlmn. the first is a translation of vertex h to vertex l. what is the second transformation? a reflection across the line containing hk a rotation about point h a reflection across the line containing hj a rotation about point k

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
