What about the electric potential energy

Reference no: EM138828

Q1. If the proton is released from rest in a uniform electric field, does equivalent electric potential at the proton's changing locations increase or decrease? What about the electric potential energy.

Q2. A 2.16 kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0320 m. The spring has force constant 840 N/m. The coefficient of kinetic friction between the floor and the block is 0.81. The block and spring are released from rest and block slides along the floor.What are the speed of block while it has moved a distance of 0.0180 m from its initial position?
