Do we have a formula to work with, or is there more information?

anonymous · Answer

its only info

amistre64 · Answer

since its in feet we use -16t^2 +initial velocity(t)+initial height

amistre64 · Answer

h(t) = -16t^2 +42t

go amistre! you can do it!

amistre64 · Answer

lol :)

max height occurs when t = 42/32

amistre64 · Answer

42/32 = 21/16 right?

-16(21/16)^2 +42(21/16) = abt 27.56....ft

myininaya · Answer

21*2=42
16*2=32

so yes!
