sound = 340 m/s1

11.47 seconds is the answer.
given height,s=500m
g=10
speed of sound =340
upon analyzing we get that
we have to find time period
first analyze the data and apply different formulas for it then see which formula suits the best.
the formula that should be used
s=ut+1/2at2
u=0,
500=0+1/2x10xtxt
we get t=10 sec
now the time for the resound=500/340=1.47 sec
total time=10+1.47=11.47 sec
hope this helped!!

Barry, I told you,
stop flying in the house!
– Hey, Adam.
– Hey, Barry.
