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.

As per kinematics equation we are given that

v^2 = v_o^2 + 2ax

now we are given that

a = 2.55 m/s^2

v_0 = 21.8 m/s

v = 0

now we need to find x

from above equation we have

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

0 = 475.24 + 5.1 x

x = 93.2 m

so it will cover a distance of 93.2 m

Answer:

x = -93.18 meters

Explanation:

The equation is given as :

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

The known values are as follows:

a=2.55\ m/s^2

v_o=21.8\ m/s

v=0\ m/s

Putting all the values in equation (1) as :

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

x = -93.18 meters

So, the vale of x is 93.18 meters. Hence, this is the required solution.

Answer:

The location of the survey is biased.

Explanation:

If someone left a movie theater, it is most likely because he likes watching movies there. A better place to interview would be on the streets, as it’s less biased there

Objects 1 and 2 attract each other with a electrostatic force
avanturin [10]

Answer:

F = 144 units

Explanation:

For this exercise we use coulomb's law, for the initial conditions

           F₀ = k \frac{q_1q_2}{r_o^2}

indicate that the force F₀ = 36.0 units and the distance is reduced to r = r₀/2 which is the new force

          F = k \frac{ q_1q_2 }{(r_o/2)^2}

           

we substitute

          F = 4 k \frac{q_1q_2}{r_o^2}

          F = 4 F₀

we calculate

          F = 4 36

          F = 144 units
