A0.20-kg mass is oscillating on a spring over a horizontal frictionless surface. when it is at a displacement of 2.6 cm for equilibrium it has a kinetic energy of 1.4 j and a spring potential energy of 2.2 j. what is the maximum speed of the mass during its oscillation?

answer; i believe that the correct answer is (d) a very small amount of mass

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

  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.
