I don't have the official mark scheme. I do have the answers:

1) R=294NR= 294N

2)
i) 2.0ms−12.0 ms^{-1}

ii) 4s4s

iii)1.67ms−11.67ms^{-1}

3)
i) v=0.12t−0.0003t2v=0.12t - 0.0003t^2

ii) 3200m3200m

4)
i) α=73.7degrees\alpha=73.7degrees

ii)175N175N

iii) 3.01m3.01m

5)
i) R=63NR=63N
angletohorizontal=75.7degreesangle to horizontal = 75.7degrees


ii) X=18.9NX=18.9N

iii) In this situation R is smaller. Since F=μRF = \mu R, it follows that F is smaller. Hence, X is smaller.

6)
i) a=2.8ms−2;T=6.3Na=2.8ms^{-2}; T=6.3N

ii) 1.152m1.152m

iii)0.457s0.457s
