i thnk v r supposed to do this way:
gain in PE = WD by driving force + KE -WD against resistance
12500*10*h = 3300000+2100000-2400000
h = 24m

[(i hv convrtd the values into joules i dnt undrstand y i cnt do it wen in KJ:/)
WD =F*d
WD against resistance = 4800*500 = 2400000]

cant solve Q:1 P42 oct/nov/09 Q:3 , 5 and 7 Oct/Nov/2010 P42 plzzzzzzzzzz help . . .. . . . .

 

[Lyfroker]

This is for Nov-09
1 (a.i.)
2+2+3=7
cost of meat= (2/7)*x=$2.40
Total cost= 2.4*(7/2)
= 8.4

(ii)(x/100)*20=8.4
x = 8.4*(100/20)
x = 42 %

(b) 1+8+3=12

veg=(8/12)*9
= 6

(c) cost of fruit= (3/7)*8.4 = 3.6
mass of fruit= (3/12)*9 = 2.25

cost per kilogram= 3.6/2.25 = $1.6

(d) (125/100)*x = 2.4
x = 2.4*(100/125)

ummm u misunderstood . ... its mechanics P4

Please help me on Modulus :

1. Sketch on the same diagram, graphs of y = | 8x+1 | and y = 9x + 1 . Hence, find the points of intersection and solve the the equation | 8x+1 | and y = 9x + 1

VERY URGENT ! Thanks ​
