calculate the initial velocity of an object displaced 33 meters while accelerating 8 m/s^2 to a final velocity of 68 m/s how do

Grace [21]

Use the equation

${v_f}^2-{v_i}^2=2a\Delta x$

The final velocity $v_f$ is 68 m/s, the acceleration $a$ is 8 m/s^2, and the net displacement $\Delta x$ is 33 m, so you can solve for the initial velocity $v_i$ :

$\left(68\,\dfrac{\mathrm m}{\mathrm s}\right)^2-{v_i}^2=2\left(8\,\dfrac{\mathrm m}{\mathrm s^2}\right)(33\,\mathrm m)$

${v_i}^2=4096\,\dfrac{\mathrm m^2}{\mathrm s^2}$

$v_i=64\,\dfrac{\mathrm m}{\mathrm s}$

What unit is defined to express a quantity as a result of a 1 m s2 acceleration of a 1 kg object?

Dafna11 [192]

The definition of a Newton (unit) is an expression of a quantity as a result of a $1 m/s^{2}$ object acceleration.

<h3>What is the SI newton unit?</h3>

The Standard International (SI) unit of force is the newton. The letter N is frequently used to shorten the phrase "newton" in physics and engineering documents. In the absence of any other forces, one newton is the force necessary to accelerate a mass of one kilogram at a pace of one meter per second squared.

<h3>What are the equivalents of a newton in terms of mass and acceleration?</h3>

One Newton is the amount of force required to accelerate one kilogram of mass one squared meter per second.

<h3>Is the newton a measure of force?</h3>

The newton, abbreviated N, is the SI unit of force. Base units that are pertinent to force are: The symbol for the length unit of a metre is m. the kilogram (kg), a unit of mass.

The longest passenger liner ever built was the France, 66,348 tons and 315.5 long. Suppose its front end passes the edge of a pi

Kaylis [27]

Answer:

The back end of the vessel will pass the pier at 4.83 m/s

Explanation:

This is purely a kinetics question (assuming we're ignoring drag and other forces) so the weight of the boat doesn't matter. We're given:

Δd = 315.5 m

vi = 2.10 m/s

a = 0.03 m/s^2

vf = ?

The kinetics equation that incorporates all these variables is:

vf^2 = vi^2 + 2aΔd

vf = √(2.1^2 + 2(0.03)(315.5))

vf = 4.83 m/s
