fd=1/2mv^2: 390d=0.5*68*27^2 d=68.6 68.6=27^2-0/2a a=5.31m/s^2

Physics
d=1/2*10s*20m/s+1/2*20s*20m/s=100m+200m=300m avg velocity=total distance/total time=300/30=10m/s

laws of motion
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

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 moment:48R1+50=1512 R1=33.6N R2=...

The weight of an object on Earth is 350 newtons. On Mars, the same object would weigh 134 newtons. What is the acceleration due to gravity on the surface of Mars, given that it is 9.8 meters/second2 on Earth?
