Questions
A particle is projected with a velocity of 10 at an angle with horizontal. A bird moves along the path of projected particle with constant speed of 4 . Find the acceleration of bird when it is at highest point of path of particle.(g = 10)
detailed solution
Correct option is D
For Particle Mg=Mucosθ2R⇒R=u2cos2θgFor Bird, an=v2R=v2u2cos2θ×g=42102cos2370×10= 2.5 ms-2Similar Questions
