A STONE WHIRED AT THE END OF A ROPE 30CM LONG, MAKE 10 COMPLETE REVOLUTION IN 2 SECONDS. FIND A. AUGULAR VELOCITY IN RADIANS PER SECOND B.THE LINEAR SPEED C.THE DISTANCE IN 5 SECONDS
Answered by Anonymous
10 times 2 pi radians / 2 seconds = 10 pi

v = omega r = 10 pi * 0.30 meters/second
or answer to a times 0.30 meters

distance v * t = 10 pi * 0.30 * 5
or answer to b times 5 seconds

A. V = 10rev./2s * 6.28rad/rev. = 31.4 rad/s.

B. Circumference =2 pi * r = 6.28 * 0.30 = 1.884 m.
V = 10rev./2s * 1.884m/rev. =

C. d = V * t = V * 5 =
Use value of V calculated in B.
