Free Body Diagrams and Acceleration Solving for a Outline

Demo Draw the free body diagram for a mass hanging from a ceiling and supported by two strings.

Ex 2: How far did the block move after 2 seconds if it Demo Ex 1: A block of mass 5 kg is being pulled by a rope with a force of 20 N over a frictionless surface. Determine the acceleration of the block. Ex 2: How far did the block move after 2 seconds if it started from rest ?

Demo Ex 3: Two blocks are pulled with a force of 20N over a frictionless surface. Block 1 has a mass of 1kg and block 2 a mass of 3kg. What is the acceleration of the system ?

Demo Ex 4: Two blocks are connected over a frictionless pulley. What is the acceleration of the system given no friction. m1=2kg m2=1kg
