Vf = square root of (V0^2 + 2g (h0 - h1)

Vf = square root of (14 m/s)^2 + 2(9.81)(4.9)

Vf = square root of (196m^2/s^2 + 96.138

Vf = square root of (292.138)

Vf = 17.09 m/s

You've got a sign wrong somewhere. How can you coast uphill and end up faster at the top?

please tell me where i went wrong

(ho - h1) is not a positive number. You have taken it to be +4.9 m
