There is an upper limit on the speed of a particle. This means there is also an upper limit on its

Physics
1 answer:
Dafna11 [192]3 years ago
5 0

Answer:

As speed of a particle has a limit so does its momentum has a limit.

Explanation:

As we know that in this Universe no information can travel faster than the speed of light.

The speed of light is the fastest possible speed and hence the quantities dependent on it also have certain limits.

The momentum of a body at normal non-relativistic speed is given as:

p=m.v

The momentum of a body at relativistic speed (a speed of the order of speed of light) is given as:

p=m.v.\gamma

here

\gamma =\frac{1}{\sqrt{1-\frac{v^2}{c^2} }}  Lorentz factor

Two horses are pulling a barge with a mass 2000 kg along a canal. The cable connected to the first horse makes an angle of θ1= 4
Shkiper50 [21]

Answer:

a = 0.5195 m/s²

θ = 9.997º ≈ 10º

Explanation:

We apply Newton's 2nd Law as follows:

∑ Fx = m*ax

∑ Fy = m*ay

Then we have

∑ Fx = F₁x + F₂x = m*ax    ⇒ 600*Cos 40º + 600*Cos (-20º) = 2000*ax

⇒   ax = 0.5117 m/s²

∑ Fy = F₁y + F₂y = m*ay    ⇒ 600*Sin 40º + 600*Sin (-20º) = 2000*ay

⇒   ay = 0.0902 m/s²

the magnitude of the acceleration of the barge is

a = √(ax² + ay²) = √((0.5117 m/s²)² + (0.0902 m/s²))= 0.5196 m/s²

and the direction is

θ = Arctan (ay / ax) = Arctan (0.0902 / 0.5117) = 9.997º ≈ 10º

Find the acceleration of an 800-kg car that has a net force of 4,000 N acting upon it.
kotykmax [81]

Answer:

The acceleration of the car is 5m/s²

Explanation:

Given data

Force F= 4,000N

Mass of car m= 800kg

Acceleration a= ?

Applying the Newton's second law of motion which states that the rate of change of momentum of a body is proportional to the external force and takes place in the direction of the force

F=ma

a= F/m

a= 4000/800

a=5m/s²
