It means that you note down the observation at time t = t1 of some experiment which you are performing.
Answer:
0.78m/s
Explanation:
We are given that
Acceleration=
v=0, s=1 when t=0
We have to find the particle's velocity at s=2m
We know that




By using formula:

Substitute s=2




Hence, the velocity of particle at s=2m=0.78m/s
You can use apple cider vinegar. If you don't have it, you can go to shoppers drug mart and they will have an ointment to sooth itches.
Answer:
g
Explanation:
if an object is thrown upward or at any angle, the acceleration acting on that object is the same as acceleration due to gravity which always acts towards the vertically downwards direction because there is no acceleration or the force acting on the object in horizontal direction.
Thus, the acceleration is same as acceleration due to gravity g.
