Questions
A body of mass m is projected with vertical making an angle 45o with the horizontal from the point P. Its highest point is H and it returns to the ground at Q. The change in angular momentum in going from P to Q is
detailed solution
Correct option is C
|ΔL|=LQ−LP. Here LP=0∴ ΔL=LQ=r×p=R×pwhere r = R = rangeAt an angle of 45∘R=V2g and p=musin45∘=mu2∴ ΔL=V2g×mv2=mv32gTalk to our academic expert!
