Question

швидкість автомобіля масою 1.5т за 10с збільшилась від 54км/год до 72км/год визначити силу що діяла на автомобіль та щлях що проїхав автомобіль? Быстрее если можно!!!​

Answer 1

Ответ: 175м; 750Н

Объяснение:

Дано:

m=1,5т=1500кг

Vo=54км/ч=15м/с

V=72км/ч=20м/с

t=10c

-------------------

S-?; F-?

V=Vo+at

a=(V-Vo)/t=(20-15)/10=0,5м/с²

S=Vo*t+at²/2=15*10+0,5*10²/2=175м

F=ma=1500*0,5=750Н

Answer 2

Calculating Force and Distance Traveled

To calculate the force acting on the car and the distance it traveled, we can use the following information:

Initial velocity (u) = 54 km/h Final velocity (v) = 72 km/h Time taken (t) = 10 s Mass of the car (m) = 1.5 t (or 1500 kg, assuming 1 ton = 1000 kg)

First, let's calculate the acceleration of the car using the formula: \[ a = \frac{v - u}{t} \]

Substitute the given values: \[ a = \frac{72 - 54}{10} \]

\[ a = \frac{18}{10} \]

\[ a = 1.8 \, m/s^2 \]

Now, we can calculate the force acting on the car using the formula: \[ F = ma \]

Substitute the mass and acceleration: \[ F = 1500 \times 1.8 \]

\[ F = 2700 \, N \]

So, the force acting on the car is 2700 N.

Next, we can calculate the distance traveled by the car using the formula: \[ s = ut + \frac{1}{2}at^2 \]

Substitute the values: \[ s = 54 \times \frac{10}{3.6} + \frac{1}{2} \times 1.8 \times (10)^2 \]

\[ s ≈ 150 + 90 \]

\[ s ≈ 240 \, m \]

Therefore, the car traveled a distance of 240 meters.

So, the force acting on the car is 2700 N and the car traveled a distance of 240 meters.

Conclusion

The force acting on the car was 2700 N, and the car traveled a distance of 240 meters. If you have any further questions or need additional assistance, feel free to ask!
