The electric potential in a particular region of space varies only as a function of y-position and is given by the function V(y)

nikdorinn [45]

Answer:

$E = 55.9583\ Volts/meter$

Explanation:

First let's find the electric potential using y = 22.5:

$V(y) = 1.69y^2 +15.6y+52.5$

$V(22.5) = 1.69(22.5)^2 + 15.6*22.5 + 52.5$

$V(22.5) = 1259.0625\ Volts$

Then, to find the magnitude of the electric field, we just need to divide the electric potential by the distance y:

$E = V/d$

$E = 1259.0625/22.5$

$E = 55.9583\ Volts/meter$

A football field is about 100 m long. If it takes a person 20 seconds to run its length, how fast (what speed) were they running

leonid [27]

Answer:

Speed, v = 5 m/s

Explanation:

We have,

The length of the football field, l = 100 m

A person takes 20 seconds to run its length.

It is required to find the speed of the person with which he should run. The distance covered divided by time taken is called its velocity.

$v=\dfrac{d}{t}\\\\v=\dfrac{100\ m}{20\ s}\\\\v=5\ m/s$

So, the speed of the person is 5 m/s.

An object travels with velocity v = 4.0 meters/second and it makes an angle of 60.0° with the positive direction of the y-axis.

Galina-37 [17]

Vx=cos60(4)
x-component of velocity
If you think about it, it makes a right triangle when you combine all the different types of forces together such as v, vx and vy. Then, you can use trigonometry and soh cah toa in order to figure out vx.
