Questions
A particle of mass 'm' is projected with a velocity 'u' at an angle '' with the horizontal. Work done by gravity during its descent from its highest point to, the position where its velocity vector makes an angle
detailed solution
Correct option is C
As horizontal Component of velocity remains constant, work done = ΔKE along vertical direction , Ky1 = 0Tanα2=VyuCosα⇒Vy=uCosα.Tanα2Ky2=12mVy2=12mu2Cos2α.Tan2α2Talk to our academic expert!
