Chapter 4 Connected Objects

(a) the acceleration given this system

(b) the tension in the cord connecting the 3.0kg and the 1.0kg blocks

(c) The force exerted by the 1.0-kg block on the 2.0-kg block

Draw two FBD’s and write two 2nd Law Equations 30. An object with mass m1 = 5.00 kg rests on a frictionless horizontal table and is connected to a cable that passes over a pulley and is then fastened to a hanging object with mass m2 = 10.0 kg, as shown in Figure P4.30. Find the acceleration of each object and the tension in the cable. Draw two FBD’s and write two 2nd Law Equations
