Question

The length of minute hand of a clock is 14 cm.calculate the speed at which the tip of minute hand moves.

Answer 1

R = 14cm

Tip of minute clock travels distance = circumference of circle of radius 14cm in 60 minutes (= 3600 seconds)

Speed = Distance / Time
Speed = 2π*(14) / (3600)
Speed = 0.024 cm/s
