Velocity is define as how fast an object is moving, and in what direction, it is a vector quantity, meaning velocity has both magnitude and direction. Anything goes to the left is negative, and anything goes to the right is positive.

a. Direction from east to west, given distance 11.5 meters, and time of 7.10 s

V = displacement/time  V = -11.5/7.10 S  V = -1.62 m/s  (going left)

b. Joaquin reaches his original position. Displacement is now zero.

    Velocity of the lawnmower is equal to "zero" but if we calculate for the average speed of the lawn, you just have to add the distance covered and the time it take to go back at the original position or point of origin

You are designing an airplane propeller that is to turn at 2400 rpm (Fig. 9.13a). The forward airspeed of the plane is to be 75.
lidiya [134]

Answer:

r = 1.07 m

Explanation:

The maximum radius of the propeller that can be allowed is given by the following formula:

v = r\omega\\\\r = \frac{v}{\omega}

where,

r = maximum possible radius of the propeller = ?

v = maximum possible linear speed of the propeller = 270 m/s

ω = angular speed of the propeller = (2400 rpm)(2π rad/1 rev)(1 min/60 s)

ω = 251.33 rad/s

Therefore,

r = \frac{270\ m/s}{251.33\ rad/s}

<u>r = 1.07 m</u>

An infinite sheet of charge is located in the y-z plane at x = 0 and has uniform charge denisity σ1 = 0.37 μC/m2. Another infini
Firlakuza [10]

Answer:

The x-component of the electric field at point P --  31,638.41

Explanation:

Given data:

charge density \sigma_1 =0.37 \muC/m^2

Another charge density \sigma_2 = -0.19 \mu C/m^2

Electric field due to infinite sheet of charge is given as E

E = \frac{\sigma}{2\epsilon}

E_{NET} = E_1 + E_2

             = \frac{\sigma_1}{2\epsilon} + \frac{\sigma_2}{2\epsilon}

            =  \frac{0.37\times 10^{-6}}{2\times 8.85\times 10^{-12}} + \frac{0.19\times 10^{-6}}{2\times 8.85\times 10^{-12}}

             = 31,638.41
