In this lesson, we will learn how to calculate the sum of multiple forces with arbitrary directions and how to calculate the acceleration produced by such forces.
Find the acceleration of the object of mass 5.0 kg shown in the accompanying diagram.
An object with a mass of 5.0 kg accelerates at a rate of 2.0 m/s2 in the positive
-direction when two forces
are applied to it. One of the forces acts in the positive
-direction with magnitude 12.0 N. Find the magnitude of the other force.
The body shown being acted on by three forces has a mass of 10.0 kg.
Find the acceleration of the body.
A particle is accelerated when acted on by two forces,
as shown in the accompanying diagram. The force
has twice the magnitude of force
Find the direction in which the particle’s net acceleration occurs,
in terms of the angle below the negative
-direction from the position of the particle.
A body of mass 2.00 kg is pushed straight upward by a 25.0 N vertical force. What is the magnitude of its acceleration?
Two forces of 25 and 45 N act on an object. Their
directions differ by
The resulting acceleration has magnitude of
10.0 m/s2. What is the mass of the body?
Two muscles in the back of the leg pull upward on the Achilles tendon, as shown in the figure.
Find the magnitude of the total force on the Achilles tendon.
