Question

4) BRAINLIEST & 10 + POINTS! 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. ****Round to the nearest whole number. Linear speed = ____ cm/s

Answer 1

Answer:

352 cm/s

Step-by-step explanation:

same as other thing i jsut did.

Answer 2

Answer:

≈ 1106 cm/s

Step-by-step explanation:

linear speed = angular speed x radius of the rotation

• v = ωr
• v = linear speed (m/s)
• ω = angular speed (radians/s)
• r = radius of the rotation (m)

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

Given:

• d= 44 cm ⇒ r= 44/2 cm= 22 cm

• ω= 4 rev/0.5 s= 8 rev/s= 8*2π/s= 16π/s  (converted rev to radians)

Linear speed is:

• v= 22*16π cm/s ≈ 1106 cm/s (rounded to full number)
