Dynamics Questions

1. A box is pulled with 20N force. Mass of the box is 2kg and surface is frictionless. Find the acceleration of the box.

 

 

 

 

 

2. Picture given below shows the motion of two boxes under the effect of applied force. Friction constant between the surfaces is k=0,4. Find the acceleration of the boxes and tension on the rope. (g=10m/s2, sin370=0,6, cos370=0,8)

 

 

 

 

 

3. As you can see in the picture given below, two boxes are placed on a frictionless surface. If the acceleration of the box X is 5m/s2, find the acceleration of the box Y.

 

 

 

 

  

4. In the system given below ignore the friction and masses of the pulleys. If masses of X and Y are equal find the acceleration of the X?(g=10m/s2)

 

 

 5. When system is in motion, find the tension on the rope.
