If you are taking a blood pressure and the first pulse you here is at the number 123 and the last pulse you hear is at 85, how would you correctly report that person's blood pressure? (Don't
forget units)

At time t=0, a particle is located at the point (3,6,9). it travels in a straight line to the point (5,2,7), has speed 8 at (3,6,9) and constant acceleration 2i−4j−2k. find an equation for the position vector of the particle.

=force × distance a. work b. velocity c. pressure d. momentum

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?
