Learning Goal: To be able to interpret potential energy diagrams
and predict the corresponding motion of a particle. Potential
energy diagrams for a particle are useful in predicting the motion
of that particle. These diagrams allow one to determine the
direction of the force acting on the particle at any point, the
points of stable and unstable equilibrium, the particle's kinetic
energy, etc. Consider the potential energy diagram shown. (Figure

2. A 106-kg object is initially moving in a straight line with a speed of 51.3 m/s. (a) If it is brought to a stop with a decelera- tion of 1.97 m/s2, what force is required, what distance does the object travel, and how much work is done by the force? (b) An- swer the same questions if the object's deceleration is 4.82 m/s?. 3. To push a 25-kg crate up a 27° incline, a worker exerts a force of...

D. Imagine a negatively charged particle (9--0.2 C) free to move back and forth along a straight line. There are other nearby charged particles that create electric potential and electric field at all points on the line. The system is made up of the negatively charged particle and the other particles that created the potential and field. As usual, we will assume an isolated system, so that this system's...

1. A block with weight W = 30 N is on a flat horizontal surface. You pull to the right with a force F = 16 N. There is gravity present and the coefficient of friction is static = 0.4 and kinetic - 0.25. You are also pulling straight up with an applied force of 12 N. Now what are: The normal force N-_ the frictional force f- the net force on the block Foot and acceleration a = 2....
