    Projectile motion along one dimension -- urgent help needed!

    Projectile motion along one dimension -- urgent help needed!

    Not having a go at you or anything, but you know actuary is really difficult right? If you can't do engineering then you'll probably find actuary maths really difficult as well... Just my $0.02.
