1(a)[2]
scalars: energy, power and time vectors: momentum and weight [2]
1(b)(i)[1]
triangle with right angles between 120 m and 80 m, arrows in correct direction and result displacement from start to finish arrow in correct direction and labelled R [1]
1(b)(ii)[4]
1. average speed (= 200 / 27) = 7.4 m s–1 [1]
2. resultant displacement (= [1202 + 802]1/2) = 144 (m) average velocity (= 144 / 27) = 5.3(3) m s–1 direction (= tan–1 80 / 120) = 34° (33.7) [3]
