Question

the the tip of the second hand of a clock takes 60 seconds to move once on the circular dial of the clock. if the radius of the dial of the clock is 5.25, calculate the speed of the tip of the second hand​

Answer 1

Answer:

v= R × omega = 2× Pi x R / T

T = 60 sec

R= 5.25 cm = 52.5 mm

so V= 6.28×52.55/60= 5.5 mm/ sec

Answer 2

Answer:

5.5 m/s

Explanation:

hence the speed of the tip of the second hand is 5.5m/s
