Henry was given this cool toy for his birthday; he can use it to tell how fast someone is going at that moment in time. the toy must calculate the average velocity average speed acceleration instantaneous speed

Instantaneous speed

Explanation:

It is given that, Henry was given this cool toy for his birthday. He can use it to tell how fast someone is going at that moment in time. The toy must calculate the person's instantaneous speed.

Instantaneous speed of an object is defined as the speed at a particular instant. Mathematically, it is given by :

Instantaneous speed is a scalar quantity. It does not involve any direction.

So, Henry must calculate the person's instantaneous speed. Hence, the correct option is (d).

i don't know that i agree with that but what's the 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.
