v(2)=vo*2-9.8(2^2)
see if you can do the rest.
i still cant do it
b) d(2)=Vo*2-1/2 g (4)
oops, I did a error in a)
v(2)=vo -9.8*2 and vo is 4.7
c) Ok, on how far, it fell b), but the helo went up
farbelow= 4.7*2+answerinb)
okay i got the answer to b.
now is a v(2)= vo+(9.8)(2)
or
v(2)= vo -(9.8)(2)?
9.8 is a negative quantity, if up is +
so the answer to a should be -14.9 m/s
and c should be -.08?
