the plate of microwave oven accelerate from rest at a uniform rate of 0.80 rad/s

Question

the plate of microwave oven accelerate from rest at a uniform rate of 0.80 rad/s for 0.50 seconds to reach its operation speed. A) what is the angular speed? B) what is the angular displacement C) if the radius of the plate is 20 cm what is linear speed the plate of microwave oven accelerate from rest at a uniform rate of 0.80 rad/s for 0.50 seconds to reach its operation speed. A) what is the angular speed? B) what is the angular displacement C) if the radius of the plate is 20 cm what is linear speed A) what is the angular speed? B) what is the angular displacement C) if the radius of the plate is 20 cm what is linear speed

Explanation / Answer

a)

angular speed

W=Wo+alpha*t

W=0+0.8*0.5

W=0.4 rad/s

b)

x=theta

angular displacement

X=Wot+(1/2)*alpha*t2=0+(1/2)*0.8*0.52

X=0.1 rad or 0.016 rev

c)

Linear speed

V=r*W=0.2*0.4

V=0.08 m/s
