The acceleration of the truck, given it accelerated from 0 m/s to 22 m/s in 8.5 s is 2.59 m/s²

From the question given above, the following were obtained:

  • Initial velocity (u) = 0 m/s
  • Final velocity (v) = 22 m/s
  • Time (t) = 8.5 s
  • Acceleration (a) =?

<h3>How do I determine the acceleration?</h3>

The acceleration of the truck can be obtained as follow:

a = (v – u) / t

a = (22 – 0) / 8.5

a = 22 / 8.5

a = 2.59 m/s²

Thus, we can conclude that the acceleration of the truck is 2.59 m/s²

How does the 3rd Newtons Law apply to kicking a soccer ball?
tigry1 [53]
If you kick a soccer ball, you exert a force on it in a certain direction.
The soccer ball will exert an equal amount of force but in the opposite direction, which is on your foot. This is felt as ‘recoil’

Can anyone please help me with answering this question? : An accelerating (speeding up) body has a Net Force acting in the direc
Katarina [22]
That's true.

Netwon's second law states that the resultant of the forces F acting on a body is equal to the product between its mass m and its acceleration a:
\sum F = ma
This means that if the net force acting on an object is different from zero (term on the left), than the acceleration of the object (term on the right) must be different from zero as well, and therefore the body is accelerating.

In particular, both F and a in the equation are vectors: this means that if the acceleration is positive, F and a have the same direction. In this problem, the acceleration is positive (because the object is speeding up), therefore the force and the acceleration have same direction.

Answer:

  α = 5 10⁻³ rad / s²

Explanation:

For this exercise we can use Newton's second law for rotational movement, where the force is electric

             τ = I α

Where the torque is

             τ = F x r = F r sin θ

Strength is

              F = q E

The moment of inertia of a small ball, which we approximate to a point is

             I = m r²

We replace

            2 (q E) r sin θ   = 2m r² α

The number 2 is because the two forces create the same torque

             α = q E sin θ / m r

Let's reduce the magnitudes to the SI system

           m = 1.0g = 1.0 10⁻³ kg

           L = 2.0 cm = 2.0 10⁻² m

           q = 10 nc = 10 10⁻⁹ C

           E = 1.0 10 N / C

           r = L / 2

           r = 1.0 10⁻² m

Let's calculate

           α = 10 10⁻⁹ 1.0 10 sin 30 / 1.0 10⁻³ 1.0 10⁻²

           α = 5 10⁻³ rad / s²
