Seed quest 6 1
For each situation state which of the five quantities v0, vf, `ds, `dt and a are given, and give the value of each.
A ball accelerates uniformly from 10 cm/s to 20 cm/s while traveling 45 cm.
answer/question/discussion:
V0 = 10 cm/s
Vf = 20 cm/s
Ds = 45cm
Poss to directly determine vAve? Yes, because we know both v0 and vf
Poss to directly determine dv? Yes, because we know both v0 and vf
A ball accelerates uniformly at 10 cm/s^2 for 3 seconds, and at the end of this interval is moving at 50 cm/s.
answer/question/discussion:
A = 10 cm/s^2
Dt = 3 s
Vf = 50 cm/s
Poss to directly determine vAve? No, we need to know both vf and v0.
Poss to directly determine dv? No, same reason.
A ball travels 30 cm along an incline, starting from rest, while accelerating at 20 cm/s^2.
answer/question/discussion:
Ds = 30 cm
V0 = 0
A = 20 cm/s^2
Poss to directly determine vAve? No, we need to know both v0 and vf.
Poss to directly determine dv? No, same reason.
Then for each situation answer the following:
Is it possible from this information to directly determine vAve?
answer/question/discussion:
Is it possible to directly determine `dv?

I hit the enter button instead of tab. You are recieving this assignment twice.
No problem. It only took a second to delete the first attempt.
