A 20-gram bullet traveling at 250 m/s strikes a block of wood that weighs 2 kg. With what velocity will the block and bullet mov
Shkiper50 [21]

Answer:

the velocity of the bullet-wood system after the collision is 2.48 m/s

Explanation:

Given;

mass of the bullet, m₀ = 20 g = 0.02 kg

velocity of the bullet, v₀ = 250 m/s

mass of the wood, m₁ = 2 kg

velocity of the wood, v₁ = 0

Let the velocity of the bullet-wood system after collision = v

Apply the principle of conservation of linear momentum to calculate the final velocity of the system;

Initial momentum = final momentum

m₀v₀ + m₁v₁ = v(m₀ + m₁)

0.02 x 250  + 2 x 0    =    v(2  + 0.02)

5 + 0 = v(2.02)

5 = 2.02v

v = 5/2.02

v = 2.48 m/s

Therefore, the velocity of the bullet-wood system after the collision is 2.48 m/s

A fighter plane is flying overhead at mach 1.50. What angle does the wave front of the shock wave produced make relative to the
olga2289 [7]

Answer:

 θ = 41.80°

Explanation:

Given that

Mach number M= 1.5

We know that

M = u/c

Where c is the velocity of sound and u is the speed of plane

c= 340 m/s

So

u = 1.5 x 340 m/s

u = 510 m/s

We know that

sin\theta =\dfrac{c}{u}

Now by putting the values

sin\theta =\dfrac{c}{u}

sin\theta =\dfrac{340}{510}

 θ = 41.80°

So the angle will be 41.80°.

A high-speed train travels 480 km from Paris to Grenoble, France, at an average speed of 180 km/h. How long will it take to reac
hichkok12 [17]
The time (t) it will take for the train to reach to Grenoble is the quotient when the distance (d) is divided by the speed (s). That is,
                                       t = d / s
Substituting the known values,
                                       t = 480 km / 180 km/h
                                      t = 2.667 h
Thus, it will take approximately 2.7 h to reach Grenoble. The answer is letter D.
