The angular momentum of a rotating object is initially and 2s later it is .The units are in kg.m²/s.The torque that produces the change in angular momentum is E)none of the above

Question

Quizplus · Accepted Answer

The torque that produces a change in angular momentum is given by:

τ = ΔL/Δt

where ΔL is the change in angular momentum and Δt is the time interval over which the change occurs.

Substituting the given values:

ΔL = (11eaa331_f529_2255_9fad_61a54a69aa7d_TB6079_11) - (11eaa331_f529_2254_9fad_450cc45aeaf2_TB6079_11) = 11eaa331_f529_4968_9fad_c94c5a0e3865_TB6079_11

Δt = 2 s

So,

τ = (11eaa331_f529_4968_9fad_c94c5a0e3865_TB6079_11)/(2 s) = 11eaa331_f529_2257_9fad_e52d17361037_TB6079_11

Thus, the correct answer is B.

The Angular Momentum of a Rotating Object Is Initially
