(b) Block C suddenly is lifted off A. What is the acceleration of block A if Hk between A and the table is 0.11? Frictionless, massless pulley A B

A 2100 kg truck has put its front bumper against the rear bumper of a 2400 kg SUV to give it a push. With the engine at full power and good tires on good pavement, the maximum forward force on the truck is 18,000 N. What is the maximum possible acceleration the truck can give the SUV? At this acceleration, what is the force of the SUV's bumper on the truck's bumper?

The 17-Mg truck hauls the 33-Mg trailer. If the unit starts from rest on a level road with a tractive force of 25 kN between the driving wheels of the truck and the road, compute the tension T in the horizontal drawbar and the acceleration a of the rig. 33 Mg 17 Mg O O O O O Answers: T= i a= i KN m/s² O

A block of mass 1.2 kg attached to a cord running over a pulley is dragged along a level surface by a hanging mass 0.2 kg, which was originally at rest.
