Re: P2 Additional Science Next week!!well 2.2 is what i got, cross fingers it right! you had to use the mass of the boy multiplied by the speed/velocity he jumped off at and then use that answer and divide it by the speed the skateboard carried on at or something.(Original post by kILLERm)
i got 2.2kg. Doubt that's right.
55kg x 0.4= 22
22 divided by 10= 2.2kg <--(mass of skateboard) -

Re: P2 Additional Science Next week!!Can anyone briefly explain how grades work for double science? Do they take an average of every unit 2 exam we do in UMS, including the ISA and then come up with a grade? That's what I heard from my friends but would just like some conformation.

Re: P2 Additional Science Next week!!that's exactly what I put!. Also, I wrote the formula to work out mass (mass=momentum/velocity). Just to make it look better. What did you get for the kinetic energy question. I did 0.5x 120kg x 36= 2160J(Original post by EnviroProtector)
