Which of the following are appropriate acceleration units? km/hr2 m/s/s ft/s miles/hr/min sec/km/m

Km/h² or m/s/s are the appropriate units of the acceleration.

Acceleration is the rate change of velocity of an object. it is given by

a=ΔV/Δt

Δv= change in speed

Δt= time taken

Δv is measured in meter of km

Time is measured in second s or hour h

so the units of acceleration are km/h² or m/s/s

  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.
