Answer:
w = w₀ / 2 the angular velocity is half the initial value.
Explanation:
We can analyze this exercise as if we added another disk to obtain a disk with twice the mass, for which if the system is two disks, the angular tidal wave is conserved
initial instant.
L₀ = I₀ w₀
final moment
L_f = I w
the moment is preserved
L₀ = L_f
I₀ w₀ = I w
the moment of inertia of a disk is
I = ½ m R²
we substitute
½ m R² w₀ = ½ (2m) R² w
w = w₀ / 2
for the case of a disk with twice the mass, the angular velocity is half the initial value.
There is many activities you can do like running, sit-ups, push-ups, and squats.
The force experienced by the foot is 1000 N
Explanation:
We can solve the question by applying Newton's third law, which states that:
<em>"When an object A exerts a force (called action) on an object B, then object B exerts an equal and opposite force (called reaction) on object A"
</em>
In this situation, we can identify the foot as object A, and the ball as object B.
We are told that the ball experiences a 1000 N force, so the foot exerts a force of 1000 N on the ball (action). As a consequence of Newton's third law, therefore, the ball also exerts an equal and opposite force of 1000 N (reaction) on the foot.
It is important to remember that action and reaction do not act on the same object, so they never appear at the same time in the same free-body diagram (which shows only the forces acting on one object).
