The body moves without an initial speed with an acceleration of 0.4 m / s2. Determine the movement of the body

The body moves without an initial speed with an acceleration of 0.4 m / s2. Determine the movement of the body 2 seconds after the start of the movement.

Formula of uniformly accelerated motion:
V = V0 + at
Since zero speed is zero
V0 = 0
Then the formula will take the form
V = at
Substitute the resulting speed value into the path formula
S = Vt
S = at ^ 2
S = 0.4 * 4 ^ 2 = 0.4 * 16 = 6.4 m
