Answer:

The momentum of the box at t = 2 s is given as

p₂ = (-2.47î + 2.82ĵ) kgm/s

Explanation:

F = [(0.265 N/s)t] î + [(-0.460 N/s²)t²] ĵ

F = (0.265t) î - (0.460t²) ĵ

At t = 0

Initial momentum

p₀ = (-3.00 kg⋅m/s )î + (4.05 kg⋅m/s) ĵ

Find the momentum at t = 2 s

According to Newton's second law of motion, the change in momentum is equal to the impulse.

That is,

dp = F.dt

Δp = ∫²₀ F.dt

∫²₀ F.dt = ∫²₀ [(0.265t) î - (0.460t²) ĵ] dt

= [(0.1325t²) î - (0.1533t³) ĵ]²₀

= [0.1325(2²)] î - [0.1533(2³)] ĵ

∫²₀ F.dt= (0.53 î - 1.2267 ĵ) kgm/s

p₂ - p₀ = Δp = ∫²₀ F.dt = (0.53 î - 1.2267 ĵ)

p₂ = p₀ + Δp

p₂ = (-3.00î + 4.05ĵ) + (0.53 î - 1.2267 ĵ)

p₂ = (-2.47î + 2.8233ĵ) kgm/s

p₂ = (-2.47î + 2.82ĵ) kgm/s

Hope this Helps!!!

Likurg_2 [28]

Answer:

marginal cost = $2

Explanation:

given data:

cost on wool when 10 sweater made in one month = $15

cost on wool when 11 sweater made in one month = $17

fixed cost = $100

In case of no other cost present, marginal cost is given by

Marginal cost = cost of eleven sweaters - cost of ten sweaters

                       = $17 -$15

                       = $2
