An object with a mass of 5 kg is thrown with an initial velocity of 6 m/s. If the object has an initial height of 10 meters above the ground, what is the magnitude of the initial gravitational potential energy of the object? The acceleration due to gravity is 9.8 m/s2.(1 point)
90 joules
490 joules
400 joules
580 joules
Scott gave the mathematical equation which was correct and leads to the answer
490 joules :)
Hope that helps
initial gravitational potential energy = m * g * h = 5 * 9.8 * 10 ... Joules
Well, it sounds like this object is really in a high-stakes situation! Let's do some calculations to figure out the answer.
The gravitational potential energy of an object is given by the formula PE = mgh, where m represents the mass of the object, g is the acceleration due to gravity, and h is the height of the object above a reference point.
In this case, we have a mass of 5 kg, a height of 10 meters above the ground, and an acceleration due to gravity of 9.8 m/s². So, let's plug these values into the formula and see what happens:
PE = (5 kg)(9.8 m/s²)(10 m)
= 490 joules
Therefore, the magnitude of the initial gravitational potential energy of the object is 490 joules, which means the correct answer is option B: 490 joules.
Remember, gravity may be serious business, but we can still have some fun with it!
To calculate the initial gravitational potential energy (PE) of an object, we can use the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height.
Given:
Mass of the object (m) = 5 kg
Acceleration due to gravity (g) = 9.8 m/s^2
Height (h) = 10 meters
Using the formula PE = mgh, we can substitute the given values:
PE = (5 kg)(9.8 m/s^2)(10 m)
PE = 490 joules
Therefore, the magnitude of the initial gravitational potential energy of the object is 490 joules.
To find the magnitude of the initial gravitational potential energy of the object, we can use the formula:
Gravitational Potential Energy (PE) = mass (m) x gravity (g) x height (h)
Given:
m = 5 kg (mass of the object)
g = 9.8 m/s^2 (acceleration due to gravity)
h = 10 m (initial height of the object)
Substitute the given values into the formula:
PE = 5 kg x 9.8 m/s^2 x 10 m
Calculate:
PE = 490 N·m (or 490 joules)
Therefore, the magnitude of the initial gravitational potential energy of the object is 490 joules.
