Marking Scheme M1 JUNE 11:
(9709/42)
1. i)Work done= 4920 J power =97.1W,..
2. H = 4.25
3. 1048, 1360
4. Theta = 21.1, F = 11.1N, Resultant = 12N Direction = 30 deg below horizontal
5. Set of values of t = 0.7<t <1.2, velocity of Q=-1 P=4
6. T=5, R=7, f.f=4, COEF =0.571
7.i) t=100s s=110 Part ii ) at t =64.05 v = 1.16 .. iii) a=0.132
Say thanX to meh Also
Wish U Best Of Luck!!
