Answer:
4kg=4000,8m=60 times 8 =480
4000 times 480 over 100 =19200
Answer :the resultant of two vectors can be found using either the parallelogram method or the triangle method. don't know if this was helpful ?
Explanation:
The speed of the proton is
Data;
- potential difference (A) = 3500V
- potential difference (B) = -1500V
<h3>Velocity of The Proton</h3>
The work done to move through a potential velocity 'v' is q
The potential difference 'v' is the difference between A and B
But the work is converted into kinetic energy of proton.
Let's substitute the values and solve for the velocity
The speed of the proton is

Answer:
\alpha = \frac{2F}{3m} \ \frac{1}{r}
maximmun x =r
Explanation:
In this exercise we are asked for the maximum angular acceleration, let's start by writing the second law of / newton for rotational motion. Let's fix our reference system at the midpoint of the bar that has a length 2r
Σ τ = (I₁ + I₂) α
where I₁ and I₂ moment of inertia of the capsule with masses m and 2m, respectively. Let's treat these capsules as point particles
I₁ = m r²
I₂ = 2m r²
the troque of a pair of force is the force times the distance perpendicular to the point of application of the force which is the same for both forces, we will assume that the counterclockwise rotation is positive
Στ = F x + F x
the angular acceleration is the same because they are joined by the bar of negligible mass, let us substitute
2 F x = (m r² + 2m r²) α
α =
α =
let's analyze this expression
* for the application point in the center (x = 0) at acceleration is zero
* for the point of application of the torque at the ends the acceleration is
this being its maximum value
