A box is under the influence of two (and only two) forces. Julio is pulling the box to the left. A conservative force (exerted by somethingother than Julio) is pulling the box to the right. Julio moved the box a distance of 0.35 meters to the left. Which of the followingstatements correctly describes the physics of the situation as he moved the box?O The potential energy of the system decreased as the conservative force did negative work.O It is impossible to know without more information.O The potential energy of the system increased as the conservative force did negative work.O The potential energy of the system increased as the conservative force did positive work.O The potential energy of the system decreased as the conservative force did positive work.

Hooke's law describes an ideal spring. Many real springs are better described by the restoring force (FSp), -kAs-q(As), where g is a constant. Consider a spring with k = 200 N/m and q = 750 N/m³. ▼ Part A How much work must you do to compress this spring 15 cm?

A 1900-kg pile driver is used to drive a steel beam into the ground. The pile driver falls 6.00 m before coming into contact with the top of the beam, and it drives the beam 9.0 cm farther into the ground as it comes to rest. Using energy considerations, calculate the average force the beam exerts on the pile driver while the pile driver is brought to rest. N
