Let
F 1= 10 pound
F 2 = 20 pound
Angle between the two = 60 degrees
Resultant = sqrt ( 10*10 + 20*20 - 2*10*20 Cos 60)
=sqrt (300 ) pound = 17.32 pound
And Direction is theta = arctan(20/10)
Therefore theta = 63.43 degrees.

3. An object is acted upon by two forces of magnitude 10N and 8 N at an angle of 60° to each other. Draw the two vectors and the resultant. [15.62N at 26.33º to the 10N force]
An object, moving along the
circumference of a circle with radius R, is acted upon by a force
of constant magnitude F. The force is directed at all times at a 30
angle with respect to the tangent to the circle as shown in the
figure .
Determine the work done by this force when
the object moves along the half circle from A to B.
Express your answer in terms of the
variables , , and appropriate constants.

A plastic ball in a liquid is acted upon by its weight and by a buoyant force. The weight of the ball is 4.7 N. The buoyant force has a magnitude of 8.9 N and acts vertically upward. At a given instant, the ball is released from rest. The acceleration of the ball at that instant, including direction, is closest to: A plastic ball in a liquid is acted upon by its weight and by a buoyant force. The weight...
