# Physics, What is the maximum height above sea level reached by the rocks?

o Volcanoes on the Earth eject rocks at speeds of up to 250 m/s. Consider a 1250 m high volcano which ejects rocks in all directions. What is the maximum height above sea level reached by the rocks?

x is maximum when velocity is 0

v final = v initial + at

0 = 250 - 9.81 t

t = 25.484 s

x final = x initial + v initial t + 0.5at^2

x = 1250 + 250 (25.484) + 0.5 (-9.81)(25.484)^2

x= 4435.525 meters

on the 2d sea point is growing to be approximately 0.2cm a three hundred and sixty 5 days, so there isn't any rush. At an extremely tough estimate from what ive heard, the sea will probable upward thrust a million-2m in 50 years. There returned, if an ice age is prompted in the previous then the sea point will dramatically fall returned. you will desire to be high quality 5m above.
