fd=1/2mv^2: 390d=0.5*68*27^2 d=68.6 68.6=27^2-0/2a a=5.31m/s^2
d=1/2*10s*20m/s+1/2*20s*20m/s=100m+200m=300m avg velocity=total distance/total time=300/30=10m/s
for balance:clockwise moment=anticlockwise moment:using one edge of knife as reference: L*10=38*24 L=91.2N (2)R1+R2=38+25+5=68N using one support:clockwise movement=48R1+5*10 anticlockwise moment=(25+38)*24 clockwise moment equals anticlockwise
since the force applied gives the body kinetic energy from rest:fd=1/2mv^2 d=1/2at^2 250=1/2a(5)(5) a=20m/s^2 since body start from rest u=0:a=v/t 20=v/5 v=100m/s from the equation:f(250)=1/2*0.9*100^2 250F=4500 F=18N
