5 Question 10 of 35
Shelley the walrus is swimming at a speed of 1.8 m/s. Her kinetic energy is 1458 J. Calculate Shelley's
mass. Use the symbol equation below to help you. You may need to rearrange the equation.
Enter your answer as a number
kg

54 kg

Explanation:

just because my brother did this test and had the same question

  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.
