Homework Statement
Sarah shoots a toy dart vertically downward at 10.4 m/s at Mark standing on the ground below. Calculate the dart's velocity after 1.3 seconds.
Homework Equations
V=Vo + at
X=1/2(Vo -V)T
X=VoT + 1/2at2
V2=Vo2 + 2ax
(If a 2 is after a letter then it means squared)
X=displacement
A=Acceleration
T=Tome
Vo=Initial Velocity
V=Velocity
The Attempt at a Solution
Vf = (10.4 m/s) + (-9.81 m/s^2)(1.3 sec) = 23.15 m/s
That answer is wrong.
Thanks.
