Memo additions: Grade 12 P1 Q3.2

In view of the fact that this is an isolated system, accept additions 1, 2 and 3 below for full marks, because the mass does not influence the required speed.

BUT

• If 1,59 kg AND 1,6 kg are used in the substitution step, maximum 3/5 if everything else is correct. See example 1.
• If any other mass is used in the substitution step instead of 1,59 kg and/or 1,6 kg, penalise each error as indicated in the memo.
