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.

Options

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

ABC

Explanation

`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
