You have a system of a positively and a negatively charged objects (+q and -9.) separated by distance d. (a) What is the sign of the electric potential energy? (b) What can you do to increase the electric potential energy of the system? (C) What can you do to decrease the electric potential energy of the system? Support your answer with a bar chart and mathematically. Specify initial and final states on the bar chart.

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
