Frank has a mass of 100 kg, and his petite wife, Jo, has a mass of 50 kg. While on vacation, they decide to try bungee jumping. Frank nearly touches the ground on his jump, and he bounces up and down six times in 30 seconds. Required:
a. How far do you think Jo will fall, compared to Frank?
b. In 30 seconds, do you think Jo will bounce up and down more times or fewer times than Frank?

  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.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

inverse v=i*r
