The body moves uniformly accelerated with an acceleration of 1m / s²; initial velocity is zero.

The body moves uniformly accelerated with an acceleration of 1m / s²; initial velocity is zero. What is the body’s velocity 5s after the start of movement?

1) For uniformly accelerated motion with a known acceleration, the speed depends on time as follows: v (t) = v0 + a * t, where v0 is the initial velocity of the body, which in this problem is zero, a is the acceleration, t is the time of motion.
2) Then we have by this formula: v = 0 m / s + 1 m / s2 * 5 s = 5 m / s.
ANSWER: 5 m / s.
