A man unloads a 4.0-kg box from a moving van by giving it an initial speed of 1.1 m/s down a ramp that makes an angle of 18° with the horizontal. It slides with negligible friction for 2.3 m along the ramp before reaching the man's helper. What is the speed of the box as the helper catches it?

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

  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.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
