9. The picture below shows a rod of mass 4.50 kg which is free to rotate horizontally about one end at point O (the picture is a top view) with two forces acting on it as shown. a. What is the net torque on the rod due to the two F2 = 24.0 N F, = 12.0 N forces? b. What is the angular acceleration of the rod? If this angular acceleration remains constant and the rod is initially at rest, then what is the roď's kinetic energy 30.0% C. 2.50 m 3.50 m after 12.5 s? 10. The picture below shows a 1.75 kg box pressed against a spring whose spring constant is 275 N/m compressing the spring a distance of 0.225 m. When released the box slides along a frictionless surface and down a ramp. After reaching the bottom of the ramp, the box slides for a short distance before encountering a rough patch of floor where friction brings the box to a stop after 1.35 m. a. How fast is the box moving when it reaches the bottom of the ramp before encountering the rough patch? b. What is the magnitude of the…
