Question

An object is simultaneously acted upon by two forces: directed to the east and directed to the north. These forces act on the object for 7 seconds. What is the magnitude of the resultant impulse caused by the two forces?

To calculate the magnitude of the resultant impulse caused by the two forces, we can use the following steps:

Calculate the net impulse from each force.

The impulse is given by:

Where:

is the force,

is the time interval the force acts.

For , the force to the east:

For , the force to the north:

Find the resultant impulse.

Since the forces are perpendicular to each other (east and north), the resultant impulse is the vector sum of the individual impulses. We can use the Pythagorean theorem to calculate the magnitude of the resultant impulse :
