SUMMARY

The discussion centers on a physics problem involving a hot-air balloon rising at a speed of 2.51 m/s, with a compass dropped from a height of 3.01 m. The correct time for the compass to hit the ground is calculated using the equation y = y0 + v0Δt + 1/2aΔt². The final solution confirms that the time elapsed before the compass reaches the ground is approximately 0.925 seconds, correcting an initial miscalculation of 0.014 seconds.

PREREQUISITES

Homework Statement

A hot-air balloon is rising upward with a constant speed of 2.51m/s. When the balloon is 3.01m above the ground, the balloonist accidentally drops a compass over the side of the balloon. How much time elapses before the compass hits the ground?

Homework Equations

y=ynot+vnotΔt+1/2aΔt^2



The Attempt at a Solution

i used the quadratic equation to find t which was 0.014s
but i don't know where to go from here i have to find the rang but when i do that i get wrong answer
 
Physics news on Phys.org
actually iam getting the t to be 0.925s
 
wrong math on that ...now its right!
