A particle is moving in a circular path with a constant speed. Starting from $θ = 0$ , the change in the linear momentum of the particle is zero when the angular displacement $θ$ equals

Options:

Answer:

Solution:

$∣Δ P ∣ = 2 m v sin \frac{θ}{2} = 0 when sin \frac{θ}{2} = 0,$
i.e. $θ = 36 0^{\circ}$ (one full revolution, back to the initial velocity).
