The total force acting on a Volga car weighing 1400 kg is 2800 Newtons. What is the change in speed of this car in 10 seconds?
Task data: m (the mass of the Volga car) = 1400 kg; Fр (resultant of all acting forces) = 2800 N; t (movement time) = 10 s.
1) Acceleration of the Volga car (Newton’s second law): a = Fр / m = 2800/1400 = 2 m / s2.
2) Change in speed: ΔV = a * t = 2 * 10 = 20 m / s.
Answer: In 10 seconds of motion, the speed of the Volga car increased by 20 m / s.
