7 0

Answer:

0 N

Explanation:

According to Newton's first law of motion, an object in motion stays in motion until acted upon by an unbalanced force. With no friction in space to unbalance the cannonball, it will continue to keep going.

What's the average speed of an object moving 3790 meters in 249 s.

NISA [10]

Heya!!

For calculate velocity, lets applicate formula

$\boxed{d = v * t}$

<u>Δ Being Δ</u>

d = Distance = 3790 m

t = Time = 249 s

v = Velocity = ?

⇒ Let's replace according the formula and clear "v":

$\boxed{v= 3790\ m / 249\ s}$

⇒ Resolving

$\boxed{ v = 15,22 \ m/s }$

Result:

The velocity is <u>15,22 meters per second.</u>

Good Luck!!

Phoenix [80]

Velocity depends on the straight-line distance between your start-point and your end-point, regardless of what route you follow to get there.

If you stop at the same point where you started, then that distance is zero, no matter how far you drove before you returned to your start-point.

So the average velocity around any "CLOSED" path is <em>zero. (A)</em>

question how does the gravitational field gx at the surface of planet x compare with the gravitational field gy at the surface o

siniylev [52]

The gravitational field gx at the surface of planet x (M/m)(r/R)² times the gravitational field gy at the surface of planet y.

<h3>What is gravitational field?</h3>

A gravitational field, as defined by physics, is the influence a massive body has on the area surrounding it, exerting a force on another huge body. In other words, a gravitational field, which is measured in newtons per kilograms (N/kg), aids in the explanation of gravitational field.

Now, Let planet x has mass M and radius R: then gravitational field at the surface of planet: gₓ = GM/R².

Let planet y has mass m and radius r: then gravitational field at the surface of planet: $g_y$ = Gm/r².

Hence, gₓ/ $g_y$ = (M/m)(r/R)².

So, the gravitational field gx at the surface of planet x (M/m)(r/R)² times the gravitational field gy at the surface of planet y.

An air-track glider undergoes a perfectly inelastic collision with an identical glider that is initially at rest. what fraction

Allisa [31]

In this collision, 1/2 of the initial kinetic energy of the first glider is converted into thermal energy.

<h3>In plain English, what is kinetic energy?</h3>

An object's strength as a result ofstrength an object has as a result or motion is known as kinetic energy. Toorder to accelerate an object, a force must be applied. Applying force requires effort on our part. When the work is done, power is transported to the thing, which causes it to move at the athe new, constant pace.

<h3>What does kinetic energy mean, or what are some instances?</h3>

The motion energy is known as kinetic energy, and it is manifested when a particle, object, or group if particles moves. Any moving object uses kinetic energy, including people walking, baseballs being thrown, food falling from tables, and charged particles in electric fields.
