- Paper 2
A ball is thrown vertically upward at 12 m/s. Calculate its maximum height. [2 marks]
Student answer: h = 144 ÷ 9.8 = 14.7 m
Mark scheme: 1 of 2
- M1 Uses v² = u² − 2gh with v = 0 (mark earned)
- A1 Height = 7.3 m, with a correct unit (mark not earned)
To fix: you missed the 2 in 2g, so divide 144 by 19.6.
