Answer:
The answer is explained below in explanation
Explanation:
Whenever light falls on a colored surface, that color of light is reflected by the surface and all the other colors are absorbed. That is a black body appears black in all lights, because it absorbs every color and a white surface appears to be of the color of the light shone upon it because it is the mixture of all colors of light and reflects every color. The eyes only see the reflected light colors. The absorbed colors are not apparent to the eyes.
<u>Hence, when the white bulb is seen through red sunglasses, it does look like red to our eyes, while all the other colors are absorbed by the sun glasses.</u>
The momentum, in the x-direction, that was transferred to the more massive cart after the collision is 19.38 kgm/s.
<h3>Momentum transfered to the more massive cart</h3>
The momentum transfered to the more massive cart is determined by applying the principle of conservation of linear momentum as shown below;
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
where;
- m₁ is the mass of the smaller cart
- u₁ is the initial velocity of the samller cart
- m₂ is the mass of the bigger cart = 3m₁
- u₂ is the initial velocity of the bigger cart
- v₁ is the final velocity of the smaller cart
- v₂ is the final veocity of the bigger cart
⁻ΔP₁ = ΔP₂
ΔP₂ = m₂v₂ - m₂u₂
ΔP₂ = m₂(v₂ - u₂)
ΔP₂ = 3m₁(v₂ - u₂)
ΔP₂ = 3 x 3.8 x (1.7 - 0)
ΔP₂ = 19.38 kgm/s
Thus, the momentum, in the x-direction, that was transferred to the more massive cart after the collision is 19.38 kgm/s.
The complete question is beblow
A cart of mass 3.8 kg is traveling to the right (which we will take to be the positive x-direction for this problem) at a speed of 6.9 m/s. It collides with a stationary cart that is three times as massive. After the collision, the more massive cart is moving at a speed of 1.7 m/s, to the right.

I have some notes here that might help you answer the problem on your own:
<span>α = <span>dω / <span>dt
</span></span></span>Angular acceleration is derivative of angular velocity the same way as linear acceleration is derivative of linear velocity<span>
a = <span>dv / <span>dt
I hope my answer has come to your help. God bless and have a nice day ahead!</span></span></span>
