| How long will it take for a body with a mass of 100 grams to change its speed from 5 m / s to 15 m / s under the action of a force of 0.5 N?
Task data: m (body weight) = 100 g (0.1 kg); V1 (initial speed) = 5 m / s; V2 (speed of the considered body after acceleration) = 15 m / s; F (acting force) = 0.5 N.
The time during which the body under consideration will change its speed can be calculated by the formula: t = (V2 – V1) / a = (V2 – V1) / (F / m) = (V2 – V1) * m / F.
Calculation: t = (15 – 5) * 0.1 / 0.5 = 2 s.
Answer: The body in question will change its speed in 2 seconds.
