3. in 1989, michel menin of france walked on a tightrope suspended under a
balloon nearly at an altitude of 3150 m above the ground. suppose a coin falls
from menin's pocket during his walk. how high above the ground is the coin
when its speed is 40 m/s?

does anyone know the answer ?

v 154.9= 0.9 length length s little over 154.9cm

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

  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.
