Answer:

O inertia

Explanation:

The tendency of a body to maintain its state of motion is inertia.

Inertia is the tendency of a body to remain at rest or in constant motion.

According to newtons first law of motion "a body will remain in its state of rest or constant motion unless acted upon by an external force".
The tendency of the body to remain in a state of rest or of constant motion is the inertia.
Such a body will not want to accelerate or change motion.

If the mass is displaced 0.270 m from equilibrium and released, what is its speed when it is 0.130 m from equilibrium?

puteri [66]

Answer:

The speed is 1.52 m.

Explanation:

Given that,

Displacement =0.270 m

Distance = 0.130 m

Suppose a 0.321-kg mass is attached to a spring with a force constant of 13.3 N/m.

We need to calculate the angular velocity

Using formula of angular velocity

$\omega=\sqrt{\dfrac{k}{m}}$

Put the value into the formula

$\omega=\sqrt{\dfrac{13.3}{0.321}}$

$\omega=6.43\ rad/s$

We need to calculate the velocity

Using formula of velocity

$v=\omega\sqrt{A^2-x^2}$

Put the value into the formula

$v=6.43\times\sqrt{0.270^2-0.130^2}$

$v=1.52\ m/s$

Hence, The speed is 1.52 m.

A moving small car has a head-on collision with a large stationary truck 7.3 times the mass of the car. Which statement is true

san4es73 [151]

Answer:

The car would speed off 2x's as fast as the speed of the heavy truck provided the the collision is an elastic collision where there's no or little friction occurring within the scenario.

Explanation:

Newton's law proves that an object with a greater mass can move objects of lesser mass at greater distances and speed.
