what is acceleration in feet/s^2?

anonymous · Answer

idk

dan815 · Answer

the outside world uses different measurement system :)

dan815 · Answer

look up your gravity acceleration and tell me

anonymous · Answer

Formula: h(t) = -16^2 + v0t + h0 (the zero is supposed to be down though, forget what that's called, I think an underpower or something)
-16t^2 + 30t + 2 = 0

This will not factor easily so I am going to use QF

a = -16
b = 30
c = 2

t = [ -b ±√((b^2 - 4ac))] / (2a)

t = [ -30 ±√((30^2 - (4*-16 * 2))] / -32

t = [ -30 +√( 900 + 128) ] / -32 = - .06445...toss this out (no time travel allowed)

t = (- 30 - √1028) / -32 = 1.93945

It will take approximately 1.94 seconds for the baseball to hit the ground

so your acceleration is -32 ft/sec^2?
