Question

CAN IT BE TOLDAn object with a known mass, say one kilogram, is moving from I to II with a known speed, say one meter per second. At II a force acts on the object. The force does not change the object's speed, but does change its direction of motion by 45 degrees. Is it theoretically possible to calculate how strong the force was?a) Yes, the strength of the force can be calculated (through I might not know how to do the calculation).b) No, the force cannot be calculated by anyone.

Answer 1

Yes, the strength of the force can be calculated using Newton's second law.

Step-by-step explanation:

According to Newton's second law of motion, force is equal to mass times acceleration (F = ma). In this scenario, the object's speed remains the same but its direction of motion changes by 45 degrees. Since the object's speed and mass are known, we can calculate the force using the formula F = ma. However, we need to convert the 45 degrees change in direction to radians before plugging it into the formula.

Answer 2

Take into account that the force could be calculated if there would be a change in the total momentum of the object.

In this case, you can determine the change of the momentum on x and y. With this information it would be possible to determine the force.

Then, Yes, the strength of th force can be calculated (though I might not know how to do the calculation)
