physics please help? on acceleration?

Question

non uniform acceleration
the jerk motion is defined as the rate of change in velocity with time
a)write the equation which defines the average jerk with time
b)write the units for the average jerk
c)and tell me how to sketch a graph of jerk vs time ( for the carts motion )

Answer 1

you seem to missing much of the problem statement in the post.

jerk is d(a(t))/dt

if the acceleration is linear
a(t)=k*t+C
then Jerk is k

and average jerk is
(a(t2)-a(t1))/2

units are m/s^3

c) my example is straight line

send me an email with the diagram and I'll give you a solution

Answer 2

All you are able to desire to do is %. a great and unfavorable y/x direction. in case you're picking to the main appropriate (x plane) to be beneficial and down (y plane) to be beneficial then there's a great acceleration and speed because of the fact the skier is going down the hill. you are able to the two % unfavorable or beneficial planes yet you will desire to distinguish them in the past. occasion on your confusion of speed. One motor vehicle is vacationing 10km [E] and yet another is vacationing 20km [W]. in case you have been to profit those 2 autos in an query you will desire to set one to unfavorable and one to beneficial on condition that they're in opposite guidelines. Which one you % is totally as much as you as lengthy as you're consistent jointly with your determination.
