If a missile is launched from a station 300 sea level with an initial velocity of 450 m/sec, what is the height of the missile after six seconds?

2520 m (g=10m/##s^2## )

Applying newtons formula; s=ut – ##1/2## g ##t^2## =4506-##1/2##10*36 =2520 therefore it will reach a height of 2520m after 6 sec
