The body moves with equal slowness with an initial speed of 10 m / s and a constant acceleration

The body moves with equal slowness with an initial speed of 10 m / s and a constant acceleration of 2 m / s2. How long will the body move to a complete stop.

To find the duration of movement of the body to a complete stop, we apply the formula: Vк = 0 = Vн – a * t, from where we express: t = V0 / a.

Variables: Vн – initial speed (Vн = 10 m / s); a – constant acceleration (a = 2 m / s2).

Calculation: t = V0 / a = 10/2 = 5 s.

Answer: Before a complete stop, the body had to move for 5 seconds.
