Ответ:

Ответ: 10(кг·м/с)

Объяснение:

Дано

m=1кг

V=36км/ч=10м/с

P=m*v

p=10*1=10

Ответ: 10(кг·м/с)

Answer 2

To calculate power (P), you'll need to use the formula for kinetic energy:

$E_k = \frac{1}{2} m v^2$

Where:

• $E_k$ is the kinetic energy in joules (J)
• $m$ is the mass in kilograms (kg)
• $v$ is the velocity in meters per second (m/s)

First, you'll need to convert the velocity from kilometers per hour (km/h) to meters per second (m/s) because the formula requires the velocity to be in m/s.

Given:

• Mass ($m$) = 1 kg
• Velocity ($v$) = 36 km/h

Convert velocity to m/s: $v_{\text{m/s}} = \frac{36 \times 1000}{3600} \, \text{m/s} = 10 \, \text{m/s}$

Now, plug the values into the kinetic energy formula:

$E_k = \frac{1}{2} \times 1 \, \text{kg} \times (10 \, \text{m/s})^2 = 50 \, \text{J}$

The kinetic energy ($E_k$) is 50 joules. Now, you can calculate power using the formula:

$P = \frac{E_k}{t}$

Where:

• $P$ is power in watts (W)
• $E_k$ is the kinetic energy in joules (J)
• $t$ is the time in seconds (s)

Since you didn't provide the time ($t$) over which this power is being calculated, you can't calculate power without that information. Power depends on both kinetic energy and the time taken to achieve that energy. If you have the time, you can use the formula above to find the power.
