During the game, the girl ran in a straight line with a constant acceleration of 1.6 m / s2

During the game, the girl ran in a straight line with a constant acceleration of 1.6 m / s2, while for 4 s she ran a path equal to

These tasks: a (constant acceleration with which the girl ran) = 1.6 m / s2; t (running time) = 4 s; V0 (girl’s initial speed) = 0 m / s.

We calculate the path that the girl ran in 4 seconds using the formula: S = V0 * t + a * t ^ 2/2.

Let’s perform the calculation: S = 0 * 4 + 1.6 * 4 ^ 2/2 = 12.8 m.

Answer: For 4 seconds, the girl ran a path of 12.8 m.
