Canada geese migrate essentially along a north–south direction for well over a thousand kilo-meters in some cases, traveling at

kotykmax [81]

Answer:

a) 66.4 relative to the west in the south-west direction

b) 5.455 hours

Explanation:

a)If the wind is blowing east-ward at a speed of 40km/h, then the west component of the geese velocity must be 40km/h in order to counter balance it. Geese should be flying south-west at an angle of

$cos(\alpha) = 40 / 100 = 0.4$

$\alpha = cos^{-1}(0.4) = 1.16 rad = 180\frac{1.16}{\pi} = 66.4^0$ relative to the West

b) The south-component of the geese velocity is

$100sin(\alpha) = 100sin(66.4^0) = 91.65 km/h$

The time it would take for the geese to cover 500km at this rate is

t = 500 / 91.65 = 5.455 hours

A 5.0 kg Foucalt Pendulum swings at the end of a 4.0 m long cable. The pendulum is released from a height of 1.5 m above the low

liubo4ka [24]

Hi there!

We can begin by solving for the pendulum's velocity at the bottom of its trajectory using the work-energy theorem.

Recall:
$E_i = E_f$

Initially, we just have Potential Energy. At the bottom, there is just Kinetic Energy.

$PE = KE\\\\$

Working equation:
$\large\boxed{mgh = \frac{1}{2}mv^2}$

Rearrange to solve for velocity:
$gh = \frac{1}{2}v^2\\\\v = \sqrt{2gh}\\\\v = \sqrt{2(9.8)(1.5)} = 5.42 \frac{m}{s}$

Now, we can do a summation of forces:
$\Sigma F = T - W$

The net force is the centripetal force, so:
$\frac{mv^2}{r} = T - W$

Rearrange to solve for tension:
$T = \frac{mv^2}{r} + W\\\\T = \frac{5(5.42^2)}{4} + 5(9.8) = \boxed{85.75 N}$
