A block is placed at the bottom of an incline. Its connected by a string that is running through a pulley, a second mass which hangs vertically at the top of the incline. The mass at the bottom is 3kg, and the mass hanging at the top is 5kg.
The incline is at angle of 20 . There is a coefficient of kinetic friction
between the incline and the first block of 0.13. The base of the incline is 10m long. The system is released from rest.

1. Draw free body diagrams for both blocks at the moment of release
2. Calculate the tension and acceleration of the system
3. How fast is the hanging block moving just before it strikes the ground

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

What even is this. where is the question
