A penguin of mass m falls from rest at point A. At horizontal distance d from the origin O
(A) What is the angular momentum of the falling penguin about O
(B) What torque does the weight mg acting on the penguin exert about the origin O
(A) What is the angular momentum of the falling penguin about O
(B) What torque does the weight mg acting on the penguin exert about the origin O
- 0 for (A) mu2/R for (B) where R is the height of A from ground.
- 0 for (A) and 0 for (B)
- mg td for (A) and mgd for (B)
- Since angular momentum and torque both vary continuously so it is not possible to calculate them
Answer
(C) mg td for (A) and mgd for (B)
