A projectile is projected from horizontal ground with velocity 18 ~km / hr at an angle of 60^ from horizontal. Find angular speed (in rad/s) as observed from the point of projection at the time of landing. [ g =10 ~m / s ^2 ]

Correct answer

2

Step-by-step solution

= v₁ r = u R = u 2(u )(u ) g = g 2 u = 10 2 5 1 2 =2 rad / s
