Three blocks are connected as shown on a horizontal frictionless table, and pulled to the right with a force of T3= 60 NFind the acceleration of the system and the values of T1, T2, and T3.Please answer but only if you the correct solution |
| Answer» EXPLANATION:Let a be the acceleration of the system. T 1 =M 1 a .....(1) T 2 −T 1 =M 2 a ....(2) F−T 2 =M 3 a ......(3) Adding (1), (2) and (3) we GET (M 1 +M 2 +M 3 )a=F or (10+20+30)a=60⇒a=1m/s ^2 Now , T 2 =(M 1 +M 2 )a=(10+20)(1)=30N | |
