Answer:
x = 7226.94 m
y = 1677.4 m
Explanation:
This is a classic problem of a parabolic move. Let's analyze the given data.
The speed is 300 m/s but it's fired at 55°, so the x and y component of the speed would be:
Vx = 300 cos55 = 172.07 m/s
Vy = 300 sin55 = 245.75 m/s
Now, to get the x and y components of the shell, we need to apply the following expressions:
X = Xo + Vx*t (1)
Y = Yo + Vy*t - 1/2 gt² (2)
Xo and Yo is 0, and we already have the speed in x and y, so the components are:
X = 0 + (172.07)(42)
<h2>
X = 7226.94 m</h2>
For the y component:
Y = 0 + (245.75)(42) - 1/2 (9.8)(42)²
Y = 10321.5 - 8643.6
<h2>
Y = 1677.4 m</h2><h2>
</h2>
Hope this helps
Answer:
a = 1.055 x 10¹⁷ m/s²
Explanation:
First, we will find the force on electron:

where,
F = Force = ?
E = Electric Field = 6 x 10⁵ N/C
q = charge on electron = 1.6 x 10⁻¹⁹ C
Therefore,

F = 9.6 x 10⁻¹⁴ N
Now, we will calculate the acceleration using Newton's Second Law:

where,
a = acceleration = ?
m = mass of electron = 9.1 x 10⁻³¹ kg
therefore,

<u>a = 1.055 x 10¹⁷ m/s²</u>
Answer:
Explanation:
Given
Charge per unit area on each plate(
)=
Plate separation(y)=0.013 m
and velocity is given by

where a=acceleration is given by

e=charge on electron
E=electric field
m=mass of electron
