Question

Select one:

a. <-1.5, -1>m/s^2

b. <1, 12>m/s^2

c. None of these.

d. <1.5, 1.5>m/s^2

e. <-2, -12>m/s

5-5-1-4 A slider moves in a slot at a velocity relative to the rotating disk at a rate of 1 = 3 mls. which is increasing by r=1mils in the direction shown. The disk rotates at a con stant rate of w= 2 rads about the disk's center point C. At one moment, the slider is passing through the center of the disk. What is the total acceleration of the slider at this moment? Answer(s): w r, r

Explanation / Answer

at the center of the disk, radius =0

so centripetal acceleration=w^2*r=0

hence only radial acceleration of 1 m/s^2 will remain.

direction will be along +ve x axis.

hence the correct answer will be <1,0> m/s^2

hence option C is correct.
