Homework Statement
A stone dropped from the top of a building hits the ground in 2.9 s. How high is the building?
a=9.8 m/s^2
yinitial=0
vinital=0
y=?
Homework Equations
y=1/2at^2
The Attempt at a Solution
y=1/2at^2
Plugging in what I know:
y=1/2(9.8m/s^2)(2.9s)^2
Simplifying:y=1/2(82.4) m
Answer: y=41.2 m
Is this correct? Thanks in advance for confirming! :-)
