Answer:
Explanation:
Let's use the conservation of angular momentum here. If there is a conservation the addition of both must be zero.
The momentum of inertia of both are:
The angular momentum is the product between angular velocity and momentum of inertia.
Let's solve it for ω(t).
But
- R is the radius R=D/2 = 30 cm = 0.3 m
- V is the steady speed V = 0.74 m/s
Knowing that 2π rad is a rev. We have.
The minus sign means the track is moving opposite of the car.
I hope it helps you!
I think it’s [ C ] because it not to high and it doesn’t have a lot of waves like the rest.
I hope this help sorry it it wrong but that’s what I think c:
