Hi Guys, I'm a newbie to this, so be gentle! I'm trying to work out a (simple, but I can't do it!) problem regarding a theoretical acceleration disadvantage... What is the disadvantage in acceleration when a go-kart with a 7.5HP engine is used to propel a 80kg mass to 10m/s, when compared to a 65kg mass? (assume kart mass is 110kg). Any help & workings would be most appreciated!!! Thanks.
