Question

From the origin at the same time two points being to move. The first moves on the X-axis at a speed =4 m/s, and the second on the Y axis at a spe3ed of 3 m/ sec.
A. The angular velocity of first wrt second is constant
B. The velocity of separation of the two bodies is constant
C. The velocity of separation of the two bodies after 2 sec is 5 m/s
D. The angular velocity of first wrt second after 2 sec. is 5 rad/s

Answer 1

Correct Answer - ABC

`W=(v_(rel)bot)/r=(3xx4/5-4xx3/5)/r=0`
`v_(sep)=4 cos 37^(@)+3 cos 53^(@) =16/5+9/5`
=5 m/s
