Question: A 60 kg block slides along the top of a 100 kg block. The lighter block has an acceleration of 3.8 m/s2 when a horizontal force F= 390 N is applied. Assuming there is no friction between the bottom 100 kg block and the horizontal frictionless surface but there is friction between the blocks.
Part A: Find the acceleration of the 100 kg block during the time the 60 kg block remains in contact.
Please show all work and steps I am really trying to learn this for my exam.
