A force in the +x-direction with magnitude F(x)=18.0N−(0.530N/m)x is applied to a 8.40 kg box that is sitting on the horizontal,

Fynjy0 [20]

Answer:v=7.24 m/s

Explanation:

Given

F(x)=18-0.530 x

mass m=8.40 kg

box is at rest at x=0

Distance traveled=16 m

$mv\frac{\mathrm{d} v}{\mathrm{d} x}=F=\left ( 18-0530x\right )dx$

$\int_{0}^{v}vdv=\int_{0}^{16}\left ( 18-0.530x\right )dx$

$\frac{mv^2}{2}=\left ( 18x-0530\frac{x^2}{2}\right )_0^{16}$

$v^2=\frac{288-67.841\times 2}{8.40}$

$v=7.24 m/s$

How are density and pressure related related to each other?

lawyer [7]

Answer:

The pressure is the measure of force acting on a unit area. Density is the measure of how closely any given entity is packed, or it is the ratio of the mass of the entity to its volume. The relation between pressure and density is direct. Change in pressure will be reflected in a change in density
