A metal sphere with radius ra = 1.20cm is supported on an insulating stand at the center of a hollow, metal, spherical shell with radius rb = 9.90cm . Charge +q is put on the inner sphere and charge ?q on the outer spherical shell. The magnitude of qis chosen to make the potential difference between the spheres 500V , with the inner sphere at higher potential.
Part A

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.
