Aparticle traveling in a straight line is located at the point (1, 0, −1) and has speed 3 at time t = 0. the particle moves toward the point (3, 4, 3) with constant acceleration 2i+ 4j+ 4k. find the velocity v(t) and the position r(t) of the particle at time t.

Abicycle slows down when the rider applies the brakes. what type of energy transformation is involved in this example? a. kinetic energy into heat energy b. heat energy into potential energy c. potential energy into kinetic energy d. kinetic energy into mechanical energy
