Answer:
ω₂ = 5.578 rads⁻¹
Explanation:
The moment of inertia of,
turn table =
block =
By the law of conservation of angular momentum, as no external torque acts on system the total angular momentum of the system when block sits at center and when block at the outer edge must be same.
Also to find ω, ω = 2πf where f is rpm
= 2π×63/60 = 6.597
So
I₁ω₁ = I₂ω₂
( + )×6.597 = ( + )×ω₂
ω₂ = 5.578 rads⁻¹
Answer:m1v1 + m2v2 = (m1f + m2f)vf. 3000kg(10.0m/s) + (15000kg)(0.0m/s) = (18000kg)(vf).
Explanation:
Answer:
You hang a 350 gram mass on a spring and its displaced 0.5 cm. Its spring constant is
Answer:
The engine generates a force of 11000 Newtons.
Explanation:
To determine the force, first you will need to calculate the acceleration. Acceleration is change in velocity over change in time, so in this case:
Force is then determined as
This is the forward force, i.a. one acting in the direction of the car's acceleration. we are told that there is no inefficiency in the engine and transmission, therefore this same force is generated by the engine.
⭐Hey
⭐Here we can use the formula for the body that is in free fall state. .
⭐that is
↪V = underoot 2*g*h
↪So the velocity will be ...
↪V = underoot 2 * 10 * 100
↪V = underoot 2000
↪V = 20 *underoot 5
↪V = 20 ( 2.23)
↪V = 44.6 m/s
