yea. u are correct.

8) H=m*c*(t2-t1) H=300*2.44*(20-0) H=300*2.44*20 = 14640j H=14.6kj

lol.. it is a calculator work for me

using sin rule x/sin120°=6/sin30° . sin120°= √3/2 and sin30°= 1/2 x/√3/2 = 6/1/2 2x/√3 = 12 x= 12*√3/2 x= 6√3cm.. (answer)

s=ut...(I) s=1/2ut^2...(ii) from (i) t=s/u...(iii) sub in (ii) s[1-as/2u^2]=0 as/2u^2=1 s=2u^2/a s=2*20.1^2/2.65=304.9m since t=s/u t=304.9/20.1= 15.17sec

s=2u^2/a s=2*27.3^2/2.55 s=584.54 s=ut t=s/u t=584.54/27.3= 21.41sec

s=2u^2/a s=2*30^2/2.44 s=737.7 s=ut t=s/u t=737.7/30 t=24.59sec

s=2u^2/a s=2*25.8^2/2.68 s=496.75 s=ut t=s/u t=496.75/25.8 t=19.25sec

F=mgcos@= 50*9.81*sin30= 424.8N H=250cm= 2.5m W=F*h = 424.8*2.5= 1062 J
