When the body moved along a straight section, its speed increased from 2m / s to 8m / s in 4 s. Determine the acceleration of the body.
Given: straight motion; V0 (initial speed of a given body) = 2 m / s; V (final speed) = 8 m / s; t (duration of accelerated movement) = 4 s.
Solution: To determine the acceleration of a given body, we use the formula: a = (V – V0) / t.
Calculation: a = (8 – 2) / 4 = 6/4 = 1.5 m / s2.
Answer: The acceleration of a given body was 1.5 m / s2.
