At what speed is a particle's kinetic energy twice its rest energy?
bezimeni [28]
The total energy of a particle is its rest energy plus the kinetic energy. Its formula is: Et= m^2/sqrt((1-v^2)/c^2))
The rest energy is equal to the product of mass and the square of light velocity: Er=mc^2.
When the kinetics energy is twice its rest energy this holds:
Et=Er
m^2/sqrt((1-v^2)/c^2))=<span>mc^2.
</span><span>sqrt((1-v^2)/c^2))=m/c^2
</span>=> v=sqrt(3/2)c

A bullet of inertia m traveling at speed v is fired into a wooden block that has inertia 4m and rests on a level surface. The bu
GREYUIT [131]

Answer:

F = mv²/(18d)

7

Explanation:

Momentum before collision = momentum after collision

mv = m(v/3) + (4m) V

v = v/3 + 4V

4V = 2v/3

V = v/6

The acceleration of the block is:

v² = v₀² + 2aΔx

(0 m/s)² = (v/6)² + 2ad

2ad = -v²/36

a = -v²/(72d)

The friction force is therefore:

∑F = ma

-F = (4m) (-v²/(72d))

F = mv²/(18d)

The energy dissipated during the collision is:

ΔE = 1/2 mv² − (1/2 m(v/3)² + 1/2 (4m)(v/6)²)

ΔE = 1/2 mv² − (1/18 mv² + 1/18 mv²)

ΔE = 1/2 mv² − 1/9 mv²

ΔE = 7/18 mv²

The energy dissipated by the friction force:

W = Fd

W = 1/18 mv²

The ratio is:

ΔE / W

(7/18 mv²) / (1/18 mv²)

A block is pulled across a flat surface at a constant speed using a force of 50 newtons at an angle of 60 degrees above the hori
Kamila [148]

The force of friction is 25 N

Explanation:

For this problem, we can apply Newton's second law of motion along the horizontal direction:

\sum F_x = ma_x

where

\sum F_x is the net force in the horizontal direction

m is the mass of the block

a_x is the horizontal acceleration

Here  the block is moving at constant speed, so its acceleration is zero, therefore:

a=0 \rightarrow \sum F_x = 0 (1)

The net force in the horizontal direction can be written as:

\sum F_x = Fcos \theta -F_f (2)

where

  • Fcos\theta is the horizontal component of the pulling force, with F = 50 N being the magnitude and \theta=60^{\circ} being the direction, acting forward
  • F_f is the force of friction, acting backward

Combining (1) and (2), we find the magnitude of the force of friction:

Fcos \theta -F_f = 0\\F_f = F cos \theta =(50)(cos 60^{\circ})=25 N
