4) ā†’BRAINLIEST & 10+ POINTS! ā† A wheel with diameter 44 cm completes four revolutions in 0.5 seconds. Find the linear speed of the edge of the wheel in cm per second. ā‡’Round to the nearest whole number. Linear speed = ____ cm/s

Respuesta :

thechomania

Answer:

352 cm/s

Step-by-step explanation:

circ = 44pi

speed = distance * time

distance = circ * 4 = 176pi

speed = 176pi/0.5

Answer:

ā‰ˆ 1106 cm/s

Step-by-step explanation:

linear speed = angular speed x radius of the rotation

v = Ļ‰r

v = linear speed (m/s)

Ļ‰ = angular speed (radians/s)

r = radius of the rotation (m)

------------

Given:

  • d= 44 cm ā‡’ r= 44/2 cm= 22 cm
  • Ļ‰= 4 rev/0.5 s= 8 rev/s= 8*2Ļ€/s= 16Ļ€/s Ā (converted rev to radians)

Linear speed is:

  • v= 22*16Ļ€ cm/s ā‰ˆ 1106 cm/s (rounded to full number)
