Ответ:
What we'll be calculating is the average acceleration (not to be confused with instantaneous acceleration).
Given two points, lets call them initial and final, the average acceleration is calculated as:
In which
So, we plug-in our known values:
The answer is -7.5m/s^2.
Ответ:
a) the answer is t=4 seconds
b) acceleration is zero
c) displacement= 142 m
Explanation:
Given the position of the particle
a) the time required when velocity![v=72 m/s](/tpl/images/0548/9750/812e4.png)
now we solve for time![t](/tpl/images/0548/9750/3d334.png)
b) acceleration when![v=30 m/s](/tpl/images/0548/9750/9f18d.png)
acceleration is the time derivative of velocity i.e
c) the net displacement of the particle during the interval t = 1 s to t = 4 s is
