Slope of v-t graph at any instant represents instantaneous acceleration.
Option (A) is correct.
The slope of a v-t graph at any instant represents instantaneous acceleration. velocity. position. jerk

Automotive engineers refer to the time rate of change of acceleration as the "jerk." Assume an object moves in one dimension such that its jerk J is constant. (a) Determine expressions for its acceleration a, (t), velocity v(), and position x(t), given that its initial acceleration, velocity, and position are a, vi, and x, respectively. (Use any variable or symbol stated above as necessary.) a(t) v,(t)
Find s(t), where s(t) represents the position function, v) represents the velocity function, and a(t) represents the acceleration function a(t) = -181+2, with v(o)=4 and s(0)=6 s(t)=0
An object's motion is represented by the x vs. t graph shown below Hint: Velocity is the slope of x vs. t graph, and acceleration is slope of v vs. t graph. 130 points: 5 points each r (s) t (a) a. Draw the corresponding v vs. t graph on the axes provided. b. Draw the corresponding a vs. t graph on the axes provided. c. At what times is the position a maximum (most positive)? At those times, is...
Problem 9 For the following described motion, draw a position-time, a velocity-time, and an acceleration-time graph on the grids provided: 1. Standing still at the 0.6 meter position for 1 second. 2. Walking away from the detector speeding up slowly and steadily for 2 seconds, going from rest to 1.0 m/s, at x=1.6 m. 3. Walking away from the detector steadily at 1.0 m/s for 2 seconds. 4. Coming to rest slowly and steadily over a 1 second period. 5....
Derive v(t) and x(t). Acceleration is a(v)=2v. Keep the initial velocity and position (non-zero).
GOAL Apply the definition of instantaneous acceleration D (m v (m/s PROBLEM A baseball player moves in a straight-line path in order to catch a fly ball hit to the outfield. His velocity asa function of time is shown in figure (a) Find his instantaneous acceleration at points ®, ®, and C 3 t(s) 0 23 0 STRATEGY At each point, the velocity vs. time graph is a straight line segment, so the instantaneous acceleration will be the slope of...
Show that the expression v = at, where v represents speed, a acceleration, and t an instant of time, is dimensionally correct.

At the instant shown, end A of the rod has the velocity and acceleration shown. Determine the angular acceleration of the rod and acceleration of end B of the rod USING THE INSTANTANEOUS CENTER METHOD.
Please show all your work. 5) Acceleration is to velocity as velocity is to position . aaux"# r where vr įs the instantaneous velocity. So the average acceleration is about how rapidly the instantaneous velocity is changing, and the sign tells about the direction of the change. At For the pendulum, you made estimates of the instantaneous velocity for ←2.05[s] and t= 2.5%]. Also, the average speed and average velocity estimates that you made at other times may be reasonable...
