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.
'ds=45cm
Vo=10cm/s Vf=20cm/s
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.
a=10cm/s^2
'dt=3 sec
Vf=50 cm/s
A ball travels 30 cm along an incline, starting from rest, while accelerating at 20 cm/s^2.
'ds=30cm
Vo=0cm/s
a=20cm/s^2
Then for each situation answer the following:
Is it possible from this information to directly determine vAve?
1) yes, you have Vo and Vf
2)No, not directly
3)No, not directly
Is it possible to directly determine `dv?
1)not direcly
2)not directly
3)not directly
