Record in the givens: OA=1760 m=1100 kg u=0 m/s SinѲ=opposite/hypotenuse=160/1760=1/11 K.E=1/2mv^2=1/2(1100)(v^2-0^2)=550v^2http://teachers.cie.org.uk/docs/dynamic/72493.pdf
question 5 help plz.....
Gain in P.E=mgh*sinѲ=1100*10(x-0)*1/11=1000x
Work done by driving force=gain in P.E + gain in K.E+Work done against resistance
1800x=1000x+550x^2+700x
100x=55ov^2
kv^2=x
55ok=100
k=5.5
In A.B there is no increase in height so Gain in P.E equals zero
Driving Force-Resistance=mass*acceleration
1800 – 700 = 1100a
a=1m/s^2
