Question

14. a point has simultaneous velocities represented by
u, 2u, 313, and 4u. The angle between the first
and second, the second and third and the third
and fourth are respectively 60°, 90° and 150°. The
angle the resultant velocity makes with u is​

Answer 1

Explanation:

A point has simultaneous velocities represented by u,2u, 3√3u and 4u. The angle between the first and second and third and fourth are respectively 60° 90° and 150° . The angle the resultant velocity makes with u is - 1) 120°
