FALSE - The resultant in a vector addition diagram is drawn from the tail of the first vector (the starting point) to the head of the last vector (the finishing point). INSTANTANEOUS CENTER OF ZERO VELOCITY (Section 16-6) INSTANTANEOUS CENTER OF ZERO VELOCITY (Section 16-6) For any body undergoing planar motion, there always exists a point in the plane of motion at which the velocity is instantaneously zero (if it is rigidly connected to the body). The answer is in some sense quite easy to give: The instanta-neous rate of change of the function y = f(x) at the point x 0 in its domain is: lim x→x0 ∆y ∆x = lim x→x0 f(x 0)−f(x) x 0 −x. the average velocity between two points on the path in the limit that the time and the displacement between the two points approach zero. the travel time is different for every ride. The curve of the position- time graph would contain a equation, for example, x(t) =3t -4t2. Mathematically, finding instantaneous velocity, v, at a precise instant t can involve taking a limit, a calculus operation beyond the scope of this text. If it travels for 15 seconds before impact, find the instantaneous velocity at the 10th second. How is the problem of finding distance traveled related to finding the area under a certain curve? e. TRUE - Suppose that A = 3 units and B = 4 units and that the two vectors are directed at right angles to each other. To find this slope, we draw a tangent line at the point of interest (in this case at 10 s). However instantaneous velocity is the velocity of an object at a particular point of its journey. If the velocity changes during the time interval, then this quotient is the average velocity. Instantaneous velocity at any point is the slope of the tangent at that point. It can also change with time depending on whether it is accelerating, decelerating, or moving at a constant speed. A boot is put in a 1 m stick which is attached to a b) iii. point A to point B in diagram below: Distance . b. dX would be the change in position between two times that are very close together. It may or may not lie on the body! What is velocity? At this point, instantaneous acceleration … It is the average velocity between two points on the path in the limit that the time (and therefore the displacement) between the two points approaches zero. Velocity only has magnitude. Mark a point at which you have to find instantaneous velocity, say A. Remember that velocity includes speed and direction. point A to point B in diagram below: Distance . At this point, instantaneous acceleration is the slope of the tangent line, which is zero. For t > 0, the average velocity of the object during the interval [ t , t + t] is given by. Plot a graph of distance vs. time. vave = (57.5-0) / (5 – 0) vave = 11.5 m/s. Multiplying through by ω, we have −ω × v O = Therefore, the acceleration of the particle at point B is 0. Thus, the instantaneous velocity at point B is the slope of the graph at point B, which is approximately (40m - 20m) / (3s - 0s) = 6.67 m/s. As said earlier above, this Δ t has to be near zero if we want to calculate instantaneous velocity. V(5) = 8(5) + 10.

Now d is the average velocity times t. ... at any point in time. From time t = a to t = b, the distance traveled is the change in position f(b) f(a), and the time elapsed is b a, so the average velocity is: v avg = f(b) f(a) b a: Like average velocity, instantaneous velocity is a vector with dimension of length per time. If those average velocities approach a single number, then that number will be the instantaneous velocity at that point. Ch 2.2 Instantaneous velocity/speed. In the next instant the point we considered will have velocity and another point which is very next to the previous one will have zero velocity because, otherwise if the point touching the ground is having velocity, that means the wheel is slipping not rolling. At the lower right in red is the the equation v = Delta x/Delta t. To calculate the average velocity between two points and , we divide the change of position by the change in time . If the velocity changes during the time interval, then this quotient is the average velocity. Whenever the instantaneous rate of change is negative, it illustrates that the function is decreasing at that point.
