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.
