A ball rolls from position a to position B in 15.0 seconds. What is the average velocity of the ball?
- PhilomelLv 72 months ago
3*10^8 m/s or slower.

v = D/t
v = (B-a)/15s in the direction of B
((velocity is a directed speed, it needs a direction!))

Vav = distance AB/t = 0.067AB m/sec

v = d/t
v = (distance from a to b) / (15.0 s)

No way to know, you need the distance from a to b.
