Well to find the total miles what I would do is 18 x 22 which would equal 396 so the answer would be: You can go 396mi with a car that gets 22 mpg* and holds 18 gallons

*Mpg=Miles per gallon

59. (II) The crate shown in Fig. 4-60 lies on a plane tilted at an angle A = 25.0° to the horizontal, with Mk 0.19. (a) Determin

Daniel [21]

Explanation:

a) We need to write down first Newton's 2nd law as applied to the given system. The equations of motion for the x- and y-axes can be written as follows:

$x:\;\;\;\;\;mg\sin 25° - \mu_kN = ma\;\;\;\;\;\;(1)$

$y:\;\;\;\;\;N - mg\cos 25° = 0\;\;\;\;\;\;\;\;\;(2)$

From Eqn(2), we see that

$N = mg\cos 25°\;\;\;\;\;\;\;(3)$

so using Eqn(3) on Eqn(1), we get

$mg\sin 25° - \mu_kmg\cos 25° = ma$

Solving for the acceleration, we see that

$a = g(\sin 25° - \mu_k\cos 25°)$

$\;\;\;\;= 2.45\:\text{m/s}^2$

b) Now that we have the acceleration, we can now solve for the velocity of the crate at the bottom of the plane. Using the equation

$v^2 = v_0^2 + 2ax$

Since the crate started from rest, $v_0 = 0.$ Thus our equation reduces to

$v^2 = 2ax \Rightarrow v = \sqrt{2ax}$

$v = \sqrt{2(2.45\:\text{m/s}^2)(8.15\:\text{m})}$

$\;\;\;\;= 6.32\:\text{m/s}$

El peso de un cuerpo es de 392.2 N ¿Cuál es su masa?

alexandr1967 [171]

Answer:

⇒ To find the mass, we apply the following formula:

$\boxed{ \boxed{\mathbf{m=\dfrac{w}{g} }}}$

<u>Data</u>:

➢ $\textrm{Weight(w) = 392.2 Newtons}$

➢ $\mathrm{Gravity(g) = \ 9,81\ m/s^{2} }$

➢ $\textrm{Mass(m) =\ ?}$

∴ We replace and develop:

$\mathrm{m=\dfrac{w}{g} }$

$\mathrm{Mass=\dfrac{392.2}{9.81} }$

$\mathrm{Mass =39.9\ kg }$

<h2>Body mass is 39.9 kg</h2>
