Ablock of mass 15 kg starts from rest and slides down a 20° angle inclined plane. the coefficient of kinetic friction is 0.3. after sliding a distance of 34cm, it contacts a spring of force constant 350 n/m. how far does the block compress the spring?

A2.0 μf capacitor and a 4.0 μf capacitor are connected in series across a 0.827-kv potential. the charged capacitors are then disconnected from the source and connected to each other with terminals of like sign together. find the voltage across each capacitor.
