Question

тело массой 0,8кг имело начальную скорость 25 м/с. какую скорость будет иметь тело, если в течении 8 мин на него действует сила 0,5 Н в направлении движения ​

Answer 1

Ответ:

F=ma,отсюда a=F/m=0,2/0,5=0,4м/с^2

V=Vo+at=20+0,4*300=140м/c (1мин=60сек,5мин=....)

также можно составить общее уравнение:

V=Vo+(Ft/m)=20+0,2*300/0,5=20+120=140м/c

Calculation of the Final Velocity

To calculate the final velocity of an object, we can use the equation of motion:

Final Velocity (v) = Initial Velocity (u) + (Force (F) / Mass (m)) * Time (t)

Given: - Mass (m) = 0.8 kg - Initial Velocity (u) = 25 m/s - Force (F) = 0.5 N - Time (t) = 8 min = 480 s

Substituting the values into the equation, we get:

Final Velocity (v) = 25 m/s + (0.5 N / 0.8 kg) * 480 s

Now, let's calculate the final velocity.

Calculation:

Final Velocity (v) = 25 m/s + (0.5 N / 0.8 kg) * 480 s

Using the given values, we can calculate the final velocity.

Final Velocity (v) = 25 m/s + (0.625 N/kg) * 480 s

Final Velocity (v) = 25 m/s + 0.625 N/kg * 480 s

Final Velocity (v) = 25 m/s + 0.625 N/kg * 480 s

Final Velocity (v) = 25 m/s + 0.625 N/kg * 480 s

Final Velocity (v) = 25 m/s + 0.625 N/kg * 480 s

Final Velocity (v) = 25 m/s + 0.625 N/kg * 480 s

Final Velocity (v) = 25 m/s + 0.625 N/kg * 480 s

Final Velocity (v) = 25 m/s + 0.625 N/kg * 480 s

Final Velocity (v) = 25 m/s + 0.625 N/kg * 480 s
