As shown below, an object with a mass of 5 kg is moving at a speed of 10 m/s. Another object with a mass of 10 kg is moving at a speed of 5 m/s. Which of the objects has higher kinetic energy? (1 point)
The kinetic energy of an object is given by the formula:
Kinetic energy = 1/2 * mass * velocity^2
Let's calculate the kinetic energy of both objects:
For the first object:
Mass = 5 kg
Velocity = 10 m/s
Kinetic energy = 1/2 * 5 kg * (10 m/s)^2 = 250 J
For the second object:
Mass = 10 kg
Velocity = 5 m/s
Kinetic energy = 1/2 * 10 kg * (5 m/s)^2 = 125 J
Therefore, the first object with a mass of 5 kg and a speed of 10 m/s has a higher kinetic energy of 250 J.
whats the simple answer
The object with a mass of 5 kg and a speed of 10 m/s has higher kinetic energy.
To determine which object has a higher kinetic energy, we can use the formula for kinetic energy:
Kinetic Energy (KE) = (1/2) * mass * velocity^2
Let's calculate the kinetic energy of each object:
For the first object with a mass of 5 kg and a speed of 10 m/s:
KE1 = (1/2) * 5 kg * (10 m/s)^2
= (1/2) * 5 kg * 100 m^2/s^2
= 250 J (Joules)
For the second object with a mass of 10 kg and a speed of 5 m/s:
KE2 = (1/2) * 10 kg * (5 m/s)^2
= (1/2) * 10 kg * 25 m^2/s^2
= 125 J (Joules)
Comparing the two kinetic energy values, we find that the first object with a mass of 5 kg and a speed of 10 m/s has a higher kinetic energy of 250 Joules compared to the second object.
To determine which object has higher kinetic energy, we need to use the formula for kinetic energy. The formula for kinetic energy is given as:
Kinetic Energy (KE) = (1/2) * mass * velocity^2
Let's calculate the kinetic energy of each object separately:
For the first object with a mass of 5 kg and a speed of 10 m/s:
KE1 = (1/2) * 5 kg * (10 m/s)^2
For the second object with a mass of 10 kg and a speed of 5 m/s:
KE2 = (1/2) * 10 kg * (5 m/s)^2
Now, we can calculate the kinetic energy for each object using these formulas:
KE1 = 1/2 * 5 kg * 100 m^2/s^2 = 250 J (joules)
KE2 = 1/2 * 10 kg * 25 m^2/s^2 = 250 J (joules)
By comparing the results, we can see that both objects have the same kinetic energy, which is 250 joules. Therefore, neither object has a higher kinetic energy than the other.
