Problem

Two trolleys move on a smooth floor at right angles to each other. (i) Trolley A has a mass of

1.5\,\text{kg}

and moves due east with a velocity of

3\,\text{m/s}

. Find its momentum. (ii) Trolley B has a mass of

2.0\,\text{kg}

and moves due north with a velocity of

2\,\text{m/s}

. Find its momentum. (iii) Determine the magnitude of the resultant momentum of the two-trolley system.
