A train with an initial speed of 36 km / h accelerates with an acceleration of 0.5 m / s 2. What speed will the train acquire in 20 seconds?
Data: V1 (initial speed of the train under consideration) = 36 km / h (in SI V1 = 10 m / s); a (acceleration during acceleration) = 0.5 m / s2; t (duration of movement) = 20 s.
The speed that the train in question should have acquired can be calculated by the formula: V2 = V1 + a * t.
Calculation: V2 = 10 + 0.5 * 20 = 10 + 10 = 20 m / s.
Answer: After 20 seconds of accelerated movement, the train in question will acquire a speed of 20 m / s.
