Imagine you derive the following expression by analyzing the physics of a particular system: v2=v20+2ax. The problem requires so

lving for x, and the known values for the system are a=2.55meter/second2, v0=21.8meter/second, and v=0meter/second. Perform the next step in the analysis.

Based on the kinematic formula:

v^2 = v_o^2 + 2ax

We have the following known information:

Acceleration a = 2.55 m/s²

v_0 = 21.8 m/s

v = 0

We want to determine x.

Rearranging the equation, we get:

0^2 = 21.8^2 + 2(2.55)x

0 = 475.24 + 5.1 x

x = 93.2 m

Therefore, the object travels a distance of 93.2 meters.

Answer:

x = -93.18 meters

Explanation:

The equation is:

v^2=v_o^2+2ax...........(1)

Known values are:

a=2.55\ m/s^2

v_o=21.8\ m/s

v=0\ m/s

Substituting these values into equation (1):

0=(21.8\ m/s)^2+2\times 2.55\ m/s^2\times x

The result is x = -93.18 meters

Thus, the value of x is -93.18 meters, which is the required solution.

The spring in a retractable ballpoint pen is 1.8 cm long, with a 300 N/m spring constant. When the pen is retracted, the spring
Sav [3153]

Answer:

The pen requires 7.2 mJ of energy to extend.

Explanation:

Provided:

Length = 1.8 cm

Spring constant = 300 N/m

Initial compression = 1.0 mm

Additional compression = 6.0 mm

Total compression = 1.0 + 6.0 = 7.0 mm

We need to determine the energy needed

This energy is equivalent to the variation in spring potential energy

E=PE_{2}-PE_{1}

E=\dfrac{1}{2}kx_{2}^2-\dfrac{1}{2}kx_{1}^2

Substitute the values into the formula

E=\dfrac{1}{2}\times300\times(7.0\times10^{-3})^2-\dfrac{1}{2}\times300\times(1.0\times10^{-3})^2

E=0.0072\ J

E=7.2\ mJ

Therefore, a total of 7.2 mJ is needed to extend the pen.

Initially, the magnetic domains within the nail were oriented in various directions before coming into contact with the bar magnet. Upon Taylor touching the nail to the bar magnet, the magnetic fields of those domains became aligned, thus transforming the nail into a temporary magnet.

Which statements about inertia and centripetal force are correct? Check all that apply. Inertia is always present. Inertia cause
kicyunya [3294]
Inertia is universally present. It's important to note that inertia doesn't serve as the force keeping objects in circular paths; that role belongs to centripetal force, which is not always present. Centripetal force actively pulls objects towards the center of a circle. Both inertia and centripetal force contribute to the phenomenon of circular motion. Thank you, and enjoy your day;)
