Homework Statement
A hot-air balloonist, rising vertically with a constant velocity of magnitude v = 5.00 m/s, releases a sandbag at an instant when the balloon is a height h = 40.0 m above the ground After it is released, the sandbag is in free fall. For the questions that follow, take the origin of the coordinate system used for measuring displacements to be at the ground, and upward displacements to be positive.
Compute the position of the sandbag at a time 1.25 s after its release.
Homework Equations
Velocity = Initial Velocity + Acceleration(Time)
or
The Attempt at a Solution
From the problem I have been able to obtain the following values for the equation.
a = -9.8m/s^2
V initial = 0 m/s
X initial = 40m
time = 1.25s
so plugging these values in =
Vx = 0 + (-9.8)(1.25)
Vx = -12.25 m/s
Can anyone help me determine where I am making my mistake, or if it's all wrong. :(
