A system is acted upon by two forces, and . What is the net force acting on the system?
The net force acting on the system is
A force is described as a push or pull on an object that occurs due to the interaction of one system with a different system. When two items interact, each of them experiences a force.
To calculate the net force acting on this system, combine all forces.
Add both the given forces as
(1) A spring of stiffness 13 N/m, with relaxed length 20 cm, stands vertically on a table as shown in Figure 2.36. Use the usual coordinate system, with +x to the right, +y up, and +z out of the page, towards you. (a) When the spring is compressed to a length of 13 cm, what is the unit vector ? (b) When the spring is stretched to a length of 24 cm, what is the unit vector ? (2) A different spring of stiffness 95 N/m, and with relaxed length 15 cm, stands vertically on a table, as shown in Figure 2.36. With your hand you push straight down on the spring until your hand is only 11 cm above the table. Find (a) the vector , (b) the magnitude of , (c) the unit vector role="math" localid="1668490124469" , (d) the stretch s, (e) the force role="math" localid="1668490004012" exerted on your hand by the spring.
