The body moves uniformly with an acceleration of 1.5 m / s2. The initial velocity is zero.

The body moves uniformly with an acceleration of 1.5 m / s2. The initial velocity is zero. What is the speed of the body 2 s after the start of movement?

To estimate the speed of a given body after two seconds of uniformly accelerated motion, we apply the formula: V = a * t.
Variables: a – body acceleration (a = 1.5 m / s2); t – movement time (t = 2 s).
Calculation: V = a * t = 1.5 * 2 = 3 m / s.
Answer: b. After 2 seconds, the given body moved at a speed of 3 m / s.
