Its tip is 4.00 m from the center of rotation. (a) Calculate the average speed of the blade tip in the helicopter's frame of reference. m/s (b) What is its average velocity over one revolution? m/s Additional Materials Reading With the ability to measure the motion of land masses, continental drift has become an established fact. The North American and European continents are drifting apart at a rate of about 3 cm/y. At this rate how long will it take them to drift 425 km further apart than at present? yr

Explanation / Answer

here,

(a)

the total distance travelled , d = 12 - 8

d = 4 m

the total distance travelled is 4 m

(b)

the distance from start to finish is 4 m

(c)

the displacement from start to finish , s = (8 - 12)

s = - 4 m

the diplacement from start to finish is - 4 m
