The length of minute hand of a clock is 14cm. Calculate the speed with whichthe tip of the minute hand moves.
Question
The length of minute hand of a clock is 14cm. Calculate the speed with whichthe tip of the minute hand moves.
Solution
Sure, here's how to calculate the speed of the tip of the minute hand:
Step 1: Calculate the circumference of the circle that the minute hand moves around. The formula for the circumference of a circle is 2πr, where r is the radius. In this case, the radius is the length of the minute hand, which is 14 cm. So, the circumference is 2π * 14 = 88 cm (approximately).
Step 2: The minute hand moves around the entire circumference of the circle in 60 minutes (1 hour). So, the speed of the minute hand is the total distance divided by the time. In this case, the speed is 88 cm / 60 min = 1.47 cm/min (approximately).
So, the speed of the tip of the minute hand is approximately 1.47 cm/min.
