Three people pull simultaneously on a stubborn donkey. jack pulls directly ahead of the donkey with a force of 61.3 n, jill pulls with 83.9 n in a direction 45° to the left, and jane pulls in a direction 45° to the right with 137 n. (since the donkey is involved with such uncoordinated people, who can blame it for being stubborn? ) find the magnitude of the net force the people exert on the donkey.

Explanation:

It is pulled by three forces as given below

1. Jack pulls directly ahead of the donkey with a force of 61.3 N,

2. Jill pulls with 83.9 N in a direction 45° to the left, and

3. Jane pulls in a direction 45° to the right with 137 N.

Now net force directly in forward direction given as

Now similarly in perpendicular to this we have

Now net force is given by them
