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

the body's situation won't change the forces are equal opposit and on the same body

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

it would be c. predictability
