Answer:

a = 0.027 m/s²

Step-by-step explanation:

a = v₁ - v₀ / t

v₁ = 3.5

v₂ = 3.1

t = 15

then

a = (3.5 - 3.1) / 15

a = 0.4 / 15

a = 0.027 m/s²

Answer:

BC ≈ 14.7 m

Step-by-step explanation:

Using the Sine rule in Δ ABC

\frac{AB}{sinC} = \frac{BC}{sinA}

To find ∠ A subtract the 2 given angles from 180°

∠ A = 180° - (90 + 28)° = 180° - 118° = 62°

Then

\frac{7.8}{sin28} = \frac{BC}{sin62} ( cross- multiply )

BC × sin28° = 7.8 × sin62° ( divide both sides by sin28° )

BC = \frac{7.8sin62}{sin28} ≈ 14.7 m ( to 3 significant figures )
