Kallah needs to buy ribbon for a sewing project. The fabric store charges 2 dollars per meter. How much will it cost Kallah to b
2 answers:
The charge is $2/m.
We need to find how much money it costs for 75cm.
First let's change 75cm to m. There are 100cm to m.
.
Now we can create a proportion to find how much it costs for a 0.75m ribbon. Then we solve it by cross multiplying.
For some reason I can't put the dollar sign ($) in front of the 2.
It costs $1.50 to buy a ribbon 0.75m, or 75 cm long.

Hmmm the object, is at rest, when dropped, so it has a velocity of 0 ft/s
the only force acting on the object, is gravity, using feet will then be -32ft/s²,
was wondering myself on -32 or 32.. but anyhow... we'll settle for the negative value, since it seems to be just a bit of convention issues
so, we'll do the integral to get v(t) then
when will it reach the ground level? let's set s(t) = 0
part B) check the picture below
