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=10m/s vf=20m/s ds= 45cm
• 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=10m/s^2 dt=3seconds vf=50cm/s
• A ball travels 30 cm along an incline, starting from rest, while accelerating at 20 cm/s^2.
answer/question/discussion:
dt= 30cm v0=0cm/s a=20cm/s^2
Then for each situation answer the following:
• Is it possible from this information to directly determine vAve?
answer/question/discussion:
it is possible to find the answer but in some of the situations you would have to use different equations . situation 2 and 3 would not be possible without using equations to find the missing velocity.
• Is it possible to directly determine `dv?
answer/question/discussion:
no you cannot directly determine the dv without finding the missing velocity.
in the first situation you are given v0 and vf so you can find `dv.
