velocity has units of distance divided by time
a biomedical engineering exercise and need guidance to help me understand better.
A pine cone falls from a giant redwood tree. A tourist 5 meters to the side of the tree runs to catch the pine cone. It as soon as it starts to fall (immediately, ignoring reaction time). How fast must the tourist run to catch the pine cone if it falls 90 meters? Assume the runner’s velocity is constant. Report your answer in m/s.Your notion of velocity is probably similar to its scientific definition. You know that a large displacement in a small amount of time means a large velocity and that velocity has units of distance divided by time, such as miles per hour or kilometers per hour.
The minus sign indicates the average velocity
is also toward the rear of the plane.the velocity at a specific moment. A car’s speedometer, for example, shows the magnitude—but
not the direction—of the instantaneous velocity of the car. Police give tickets based on instantaneous velocity, but when calculating how long it will take to get from one place to another on a road trip, you need to use average velocity
The average velocity of an object does not tell us anything about what happens to it between the starting point and ending point, however. For example, we cannot tell from average velocity whether the airplane passenger stops momentarily or backs up before he goes to the back of the plane. To get more details, we must consider smaller segments of the trip over smaller time intervals. For instance, in the figure below, we see that the total trip displacement
