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:

≈ 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)

Answer 2

Answer:

352 cm/s

Step-by-step explanation:

circ = 44pi

speed = distance * time

distance = circ * 4 = 176pi

speed = 176pi/0.5
