An antitank weapon fires a 3.00-kg rocket which acquires a speed of 50.0 m/s after traveling 90.0 cm down a launching tube. Assuming the rocket was accelerated uniformly, what is the average force acted on it?

~4166.67 N

Explanation:

We can find the acceleration that the rocket had by using one of the constant acceleration kinematics equations.

List out the motion variables we are given:

Using the equation:

We can plug in the known variables and solve for acceleration.

Simplify this equation.

Divide both sides by 1.8.

Now we can use Newton's 2nd Law, F = ma, to determine the force acted on the rocket.

We know the mass of the rocket is 3.00-kg, and its acceleration is 1388.88889 m/s².

The average force acting on the rocket is about 4166.67 N.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
