Homework Statement
A hot-air balloon is rising straight up with a speed of 2.4 m/s. A ballast bag is released from rest relative to the balloon when it is 9.6 m above the ground. How much time elapses before the ballast bag hits the ground
known data
y direction
vo = 2.4 m/s
a = -9.8m/s
x = -9.6m
Homework Equations
v = vo + at
v-squared = vo-squared + 2ax
x = vot + 1/2a(t-squared)
The Attempt at a Solution
By plugging numbers into v-squared = vo-squared + 2ax, I got v = 13.9 m/s. Then, I plugged that and other data into v = vo + at, adn it came out to 1.17s (or 1.2s). However, I am entering this into a website which tells you whether you are right or wrong. It marked 1.2 wrong, and I only have one more guess. Is 1.17 right, or did I mess this up somehow?
