Points A (at (10,10) m) and B (at (1, 1) m) are in a region where the electric field is uniform and given by N/C. What is the potential difference

An object moves from the position +34m to the position -15m in 15 seconds. what is it's total displacement? what is it's average velocity?

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
