A force of magnitude 100N is directed N, and a second force of 200N 30 degrees East of North. Find the magnitude and direction of the third force that when added to the first two force gives a resultant where magnitude is zero.

Solution Summary

The solution shows how to find the resultant force using the component methods.

The sensor in the torso of a crash-test dummy records the magnitude of the net external force acting on it. If the dummy is thrown forward with a force of 130.0 N while simultaneously being hit from the side with a force of 4500.0 N, what force will the sensor report?

A rope is wrapped around a pole so that a force of 75 lbs acts on one end and a force of 53 lbs acts on the other end. If the angle between the two forces is 114 degrees what is the resultantforce? What angle does the resultantforce make with the 53 lbs force?

There are three forces. F1 has a magnitude of 80 N and is 30 degrees south of east. F2 has a magnitude of 60 N and is along the north direction. F3 has a magnitude of 40 N and is along the west direction. Find the resultantforce acting on the origin. Answer with magnitude and angle with respect to x-axis.

Three charges form a right triangle. A -3mC charge is 4cm above a +6mC charge. A +1/5mC charge is 3 cm to the right of the +6mC charge. What is the magnitude and direction of the resultantforce on the +6mC charge? Also find the resultantforce on the +1.5 mC charge.

Determine the resultantforce acting on the eyebolt shown in the attached figure, as a result of the four forces shown, both analytically and graphically. Compare and comment on the two results.
