yeah but then on question number 3... it says.. the values you calculaed are the average speeds for the time interval, not the speed of the interval. To be more percise, the average speed is the speed at the midpoint of each time interval, and should be plotted there instead of at the end of...

Homework Statement
in a final burst of energy near the end of a bike race, Julia accelerates at 0.32 m/s^2 north for 15 s, attaining a final speed of 18.6 m/s south. what was Julia's initial velocity and how far did she travel while accelerating?
The Attempt at a Solution
In this case I think...
What's Uniform acceleration??
Can anybody please tell me or explain to me an easy way of what uniform acceleration is? I don't understand what my teacher is telling us!:cry:
Homework Statement
When a car is being tested, it also has a braking test done/ In one such test a car took 3.0 s to stop from 40 m/s. Calculate a) the braking distance b) the deceleration
The Attempt at a Solution
first off I'm not sure how to find the braking distance and what...
Yeah, so it's 23 but i was just saying...how would i put that in the formula in the proper way...
delta t= delta v/a, delta t= (40-12)/5.0s, delta t =28m/s /5.0s = 5.6s
therefore the rocket traveled for 5.6 s?
the knowns are velocity and acceleration, yeah i know that you substitute them but would i do (40-12) to find the velcoity?
so like for (40-12) do i plug that in velocity together?

hi this is the problem: the burning of the second stage of a two stage toy rocket takes the rocket from 12 m/s to 40 m/s in 5.0s. How far does the rocket during this time?
2. Homework Equations
would i use delta t= delta v/a ? would the given info be.. delta v1=...
sorry , but i think you must be patient because all the homework helpers are helping others too. Please just wait and do your other homework questions.
Im not sure if this is the correct formula for this question, please corect me

umm well my teacher taught us this new displacement formula but i dunt think its related to the question i need help with .. but this is the formula he taught us: d= v1 deltat+1/2 a(deltat)2 sorry i dunt kno how to make the traingle for delta and the arrow heads... I am new to this
Homework Statement
Swati was driving her car over the speed limit when an oncoming car car flashes its lights warning her of a radar trap ahead. She decelerates from 39 m/s to 27 m/s in 6.0 s. What deceleration did her brakes apply?
