You glue two objects, one with a mass of 10 kg and one with a mass of 5 kg, using a glue that must be able to hold the blocks together up to a force of 19 N before failing. Suppose you then pull the 10 kg block with a force of 30 N. (a) What is the acceleration of the entire system? (b) What is the force exerted on the 5 kg block and where does it come from? Can the glue hold? (c) Now suppose you pull the 5 kg block with the force, does it make any difference in the acceleration of the system and the forces? Will the glue hold? Explain.
