The body begins to move with a speed of 4m / s. What will its speed be equal to in 2 s

The body begins to move with a speed of 4m / s. What will its speed be equal to in 2 s, if the acceleration of a moving body is 5m / s2

Given:

V0 = 4 m / s – initial velocity of the body;

a = 5 m / s ^ 2 – body acceleration;

t = 2 s – time of body movement.

It is required to find the body’s velocity V in time t.

V = V0 + a * t = 4 + 5 * 2 = 4 + 10 = 14 m / s.

Answer: After 2 seconds, the speed will reach 14 m / s.
