Which has a greater velocity? A ball rolling down a 3.4m hill in 8.5s or a fish swimming upstream, covering 6.2m in 0.6 minutes? (velocity = change in distance / change in time)

They would have the same velocity.

gigi1103 · Answer

for real t thought the fish had a higher one

mangotangochick · Answer

v = d/t 
Ball:
3.4/8.5
=0.4ms^-1

v=d/t
Fishy:
6.2/(0.6x60)
Because to find the number of seconds you do the decimal times the number of seconds in a minute
=0.172ms^1

5sos · Answer

Nope they cant compare because they are 2 different things.

gigi1103 · Answer

wait so there is no answer?

mangotangochick · Answer

You would probably have to add a sentence to each of them saying where the positive direction is (i.e. for the fish it would be upstream, but for the ball it would be down the hill)

gigi1103 · Answer

my answer choices are 	

They have the same velocity
	

the fish
	

the ball
	

they can't compare because they have different time units

You are dealing wiht 2 different "environments" you could say. It would be D!
