Margarita [4]3 years ago

Answer:

 a = 200 m/s²

Explanation:

Given,

The initial speed of rocket-powered sled, u = 0

The final speed of rocket-powered sled, v = 440 m/s

Time taken to reach final speed, t = 2.20 s

The acceleration of the body is given by the change in velocity by time

                                       a = (v - u) / t

                                          = (440 - 0) / 2.20

                                          = 200 m/s²

Therefore, the acceleration of the rocket-powered sled, a = 200 m/s²

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
