Two charges (q1 = 3.8*10-6c, q2 = 3.2*10-6c) are separated by a distance of d = 3.25 m. consider q1 to be located at the origin. 2) what is the distance in meters?

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
