Question

Calculate the angular velocity and linear velocity of a lip of minute hand of lenght 10 cm.[g=9.8 m/s²]
pls fast!

Answer 1

Given :
T = 60 min = 60 × 60 sec= 3600 sec
l = 10 cm = 0.1 m

We know that,
ω (angular velocity) = 2π/t
ω = 2× 3.142 /3600
ω = 1.744 × 10–3 rad/s

v (linear velocity) = rω
= 0.1 × 1.745 × 10–3
v  = 1.745 × 10–4 m/s
