Your pet must have current vaccinations that are required by the place (state, country, etc.) that it will be entering. Your pet would also need a health certificate that was done by a licensed veterinarian.

A Chevy is traveling 10 mph faster than a Toyota. The Chevy is traveling at a rate of 60 mph.

VikaD [51]

I think the correct answer from the choices listed above is option C. The formula that would represent the speed of the Toyota would be <span>T+10 mph= 60 mph. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>

An above ground swimming pool of 30 ft diameter and 5 ft depth is to be filled from a garden hose (smooth interior) of length 10

STALIN [3.7K]

This question involves the concepts of dynamic pressure, volume flow rate, and flow speed.

It will take "5.1 hours" to fill the pool.

First, we will use the formula for the dynamic pressure to find out the flow speed of water:

$P=\frac{1}{2}\rho v^2\\\\v=\sqrt{\frac{2P}{\rho}}$

where,

v = flow speed = ?

P = Dynamic Pressure = 55 psi $(\frac{6894.76\ Pa}{1\ psi})$ = 379212 Pa

$\rho$ = density of water = 1000 kg/m³

Therefore,

$v=\sqrt{\frac{2(379212\ Pa)}{1000\ kg/m^3}}$

v = 27.54 m/s

Now, we will use the formula for volume flow rate of water coming from the hose to find out the time taken by the pool to be filled:

$\frac{V}{t} = Av\\\\t =\frac{V}{Av}$

where,

t = time to fill the pool = ?

A = Area of the mouth of hose = $\frac{\pi (0.015875\ m)^2}{4}$ = 1.98 x 10⁻⁴ m²

V = Volume of the pool = (Area of pool)(depth of pool) = A(1.524 m)

V = $[\frac{\pi (9.144\ m)^2}{4}][1.524\ m]$ = 100.1 m³

Therefore,

$t = \frac{(100.1\ m^3)}{(1.98\ x\ 10^{-4}\ m^2)(27.54\ m/s)}\\\\$

<u>t = 18353.5 s = 305.9 min = 5.1 hours</u>

In February 1955, a paratrooper fell 362 m from an airplane without being able to open his chute but happened to land in snow, s

serious [3.7K]

Answer:

s = 0.9689 m

Explanation:

given,

Height of fall of paratroopers = 362 m

speed of impact = 52 m/s

mass of paratrooper = 86 Kg

From from snow on him = 1.2 ✕ 10⁵ N

now using formula

F = m a

a = F/m

$a = \dfrac{1.2 \times 10^5}{86}$

$a =1395.35\ m/s^2$

Using equation of motion

v² = u² + 2 a s

$s =\dfrac{v^2}{2a}$

$s =\dfrac{52^2}{2\times 1395.35}$

s = 0.9689 m

The minimum depth of snow that would have stooped him is s = 0.9689 m

You collect some data on horse racing along a straight track. You are able to fit the motion of the horse to a function during t

Digiron [165]

Answer:

The equation is missing in the question. The equation is $10 m + 5(m/s^2)t^2+3(m/s^3)t^3$

a). $v=10 t +9t^2$ , the horse will not turn.

b). a(t) = 10 + 18t

Explanation:

Given :

$x(t)=10 m + 5(m/s^2)t^2+3(m/s^3)t^3$

∴ At t =0, x = 10 m

a). Velocity as a function of time

$v = \frac{dx}{dt}$

= $10 t +9t^2$

Turning velocity must be zero.

v(t) = 0

$10 t +9t^2=0$

$\therefore t = 0 \text{ or}\ t =-\frac{10}{9}$

Taking the positive value of time.

The horse will not turn.

b). Acceleration as a function of time.

$a(t)=\frac{dv}{dt}$

= 10 + 18t

∴ a(t) = 10 + 18t
