A Problem from kinematics

The magnitude of the velocity of a particle changes uniformly from 14 m/s downward at point A to 4 m/s at point B. As the particle moves alongthe path from A to B determine the acceleration of the partice when it is at point C. Incoming search terms:kinematics magnitude of the velocity of a particle […]
