Залежність швидкості від часу в момент розгону автомобіля задано рівнянням v = 0,8t. Побудуйте графік швидкості й визначте швидкість наприкінці п’ятої секунди.

Explanation:

The question is:

A chart is a kind of graph that shows the data in bars, one beside the other, for comparison purposes. They can be either vertical or horizontal.

The heights or legnths of the bars are proportional to the value of the variable, allowing to identify the relative magnitude of the variable visually.

To create such graph, you can build a table with the times, 1, 2, 3, 4, 5, ...

    t     V(t) = 0.8t

    0            0.0

    1             0.8

    2            1.6

    3            2.4

    4            3.2

    5            4.0

    6             4.8

    7             5.6

   8             6.4

   9             7.8

  10             8.0

See the chart graph, assuming that the speed is in meter per second (m/s).

The height of each bar is the speed at the corresponding time.

The speed at the end of the fifth second is v = 0.8 × 5 = 4.0 m/s.

the force required to move the cart is divided by three or 33.33 n.
