A torque of 0.154 N*m is applied to an egg beater. If the egg beater starts at rest, what is its angular momentum after 0.504 s?
Question
A torque of 0.154 N*m is applied to an egg beater.
If the egg beater starts at rest, what is its angular momentum after 0.504 s?
Solution
To solve this problem, we need to use the formula for angular momentum (L) which is the product of the torque (τ) and the time (t) it is applied for. This is based on the principle of conservation of angular momentum, and assumes no other torques are acting on the egg beater.
The formula is: L = τ * t
Given: τ = 0.154 N*m (torque) t = 0.504 s (time)
Substitute these values into the formula:
L = 0.154 Nm * 0.504 s = 0.077616 Nm*s
So, the angular momentum of the egg beater after 0.504 s is 0.077616 Nms.
