the answer is b sorry if its wrong
Explanation:
Answer:
F = - K X force exerted by compressed spring
F X = 1/2 M V^2 energy (work) required to produce a speed V for mass M
K X * X = 1/2 M V^2 direction of F is the same as that of V
X^2 = M V^2 / K combining terms
X = (M / K)^1/2 V
X = (.92 / 130)^1/2 * 1.4 = .118 m

Explanation:
Inertia is the property of a body by virtue of which it opposes any agency that attempts to put it in motion or, if it is moving, to change the magnitude or direction of its velocity.
The more mass, the more inertia. If you increase the mass of the object then you increase the inertia.

Answer:
See below...
Explanation:
Let’s express ⟨α⟩ in terms of ωi , ωf , and Δt. and torque in terms of It , ωi , ωf , and Δt.
STEP 1.
The rate of change of angular velocity is Angular acceleration.
The net change in angular velocity is Average angular acceleration divided by the elapsed time.
⟨α⟩ = ω f −ω i/Δt
STEP 2.
Torque is assumed this way
dω
τ = I ----
dt
.
⟨τ ⟩ = I t (ω f −ω i )/Δt
The kinetic energy is found at 150 J. The work-energy theorem is applied in the given equation.
<h3>What is Kinetic energy?</h3>
The energy possessed by the body by the virtue of motion is known as Kinetic energy. It is found as the product of mass and the square of the velocity.
The given data in the problem is;
The mass is, m=0.15 kg
Force, F=300 N
Distance,d=0.50 m
From the work-energy theorem, kinetic energy is equal to the work done.
Work done = Kinetic energy
Hence, kinetic energy is found at 150 J.
