You leave your home at 1pm. At 3pm, you are 100 km east of your house. What was your average velocity in km/hr

Physics
1 answer:
Rasek [7]3 years ago
4 0

Answer:

50km/h

Explanation:

Average velocity = change in distance (or distance travelled) divided by/ the change in time (or time taken.)

The change in distance has been given as 100km.

The change in time is 3pm-1pm = 2 hours.

Therefore the average velocity was 100/2 = 50km/h (to the east).

Hope this helped!

Two identical cars are driving in opposite directions at the same speed. Their kinetic energies have _______________.
Viktor [21]

Answer: The right answer is c.

Explanation:

The kinetic energy is defined as follows:

K = 1/2 mv²

If both cars are identical, this means that they have the same mass.

Also, we are told that the speed is also the same for both cars.

If they are going in opposite directions, their velocities have the same magnitude, but opposite signs.

But even though they have different signs, the square (which is the parameter relevant for kinetic energy calculations), is always positive, as any number, elevated to an even power, is positive.

So, we conclude that both cars have the same kinetic energy, in magnitude and in sign.

The weight of a body is 147N. what is its mass?
barxatty [35]

<u>To find the mass, with only the weight</u>:

  ⇒ must consider the relationship between the mass and weight

     ⇒ (<em>in other words</em>) we must find the equation that has both the

         mass and weight

<u>Based on our physics knowledge, we know</u>:

 Weight=mass*gravitational_. acceleration

  • Weight: 147N
  • Gravitational Acceleration: 9.8 m/s²

<u>Now let's plug in the values, and solve</u>:

 147N = mass*9.8_.m/s^2\\mass = 15_.kg

<u>Answer: 15 kg</u>

Hope that helps!

<em>*as a note, if you use the gravitational acceleration as 10m/s², then the answer would be 14.7 kg</em>
