Question

Знайти імпульс вантажного автомобіля масою 10 т, який рухається зі швидкістю 36 км/год, і легкового автомобіля масою 1 т, який рухається зі швидкістю 25 м/с.​

Answer 1

Дано:

m1=10т=10000 кг

υ1=36км/год=10 м/с

m2=1т=1000 кг

υ2=25 м/с

Знайти p1, p2

p1=m1×υ1=10000×10=100000 (кг×м/с)

p2=m2×υ2=1000×25=25000 (кг×м/с)

Відповідь:p1=100000кг×м/с, p2=25000 кг×м/с.

Answer 2

Finding the Impulse of the Trucks

To find the impulse of the trucks, we can use the formula:

Impulse = Force × Time

The force can be calculated using the formula:

Force = Mass × Acceleration

And the time can be calculated using the formula:

Time = Distance / Speed

Let's calculate the impulse for each truck.

Calculating the Impulse of the Cargo Truck

The cargo truck has a mass of 10 tons and is moving at a speed of 36 km/h.

First, let's convert the speed from km/h to m/s: 36 km/h = 36 * (1000 m / 3600 s) = 10 m/s

Now, we can calculate the force: Force = Mass × Acceleration Acceleration can be calculated using the formula: Acceleration = Change in Velocity / Time Since the initial velocity is 0 m/s, the change in velocity is 10 m/s. So, the acceleration is: Acceleration = 10 m/s / 1 s = 10 m/s^2

Now, we can calculate the force: Force = 10,000 kg × 10 m/s^2 = 100,000 N

Next, we can calculate the time taken to reach this speed: Time = Distance / Speed Since we don't have the distance, we can't calculate the time or the impulse for the cargo truck.

Calculating the Impulse of the Car

The car has a mass of 1 ton and is moving at a speed of 25 m/s.

We can calculate the force: Force = Mass × Acceleration Acceleration can be calculated using the formula: Acceleration = Change in Velocity / Time Since the initial velocity is 0 m/s, the change in velocity is 25 m/s. So, the acceleration is: Acceleration = 25 m/s / 1 s = 25 m/s^2

Now, we can calculate the force: Force = 1,000 kg × 25 m/s^2 = 25,000 N

Next, we can calculate the time taken to reach this speed: Time = Distance / Speed Since we don't have the distance, we can't calculate the time or the impulse for the car.

Unfortunately, without the distance traveled by each vehicle, we are unable to calculate the time and, subsequently, the impulse for both vehicles. If you have the distance traveled by each vehicle, we can use that information to calculate the impulse.
