Answer:
v = 0.00314 m/s
Step-by-step explanation:
First we need to find the angular velocity of the second hand of the clock:
ω = θ/t
where,
ω = angular velocity = ?
θ = angular displacement
t = time taken
For 1 complete revolution:
θ = 2π radians
t = 60 s
Therefore,
ω = 2π rad/60 s
ω = 0.104 rad/s
Now, for the speed of the tip of second hand of watch:
v = rω
where,
v = speed of the tip = ?
r = radius = 3 cm = 0.03 m
Therefore,
v = (0.03 m)(0.104 rad/s)
v = 0.00314 m/s
