An ant goes from P to R on a circular path in 20 second Radius OP=10m. What is the average speed and average velocity of it ?
1) (π/6) m/s, 3 m/s 2) (π/3) m/s, √3/2 3) (π/3) m/s,√3 4) π √6
Length of arc=(2π/3) × (op) Speed=Length of arc/ time Displacement PR From figure angle POM=60° thus PM=OPsin60 PM=10 (√3 /2) Thus PR=2PM=10( √3) Velocity=PR/time=√3/2
