Atractor is being used to pull two large logs across a field. a chain connects the logs to eachther; the front log is connected to the tractor by a separate chain. the mass of the front log is 180 kg. the mass of the back log is 220 kg. the coefficient of friction between the logs and the field is approximately 0.45. the tension in the chain connecting the tractor to the front log is 1850 n. determine the tension in the chain that connects the two logs.

Explanation:

As we know that the friction force on the wooden log is given as

so we have

For front log we have

For back log we have

Now by force equation we have

so we have

now for the tension in the string between two logs we have

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
