a body of mass 5kg is thrown to a height of 100m.what is its potential energy at the maximum height.?
I Need the answer for the question pls
PE = M*g*h Joules
M = 5kg
g = 9.8 m/s^2
h = 100 m
PE = ?
To find the potential energy at the maximum height, we can use the equation:
Potential energy = mass * acceleration due to gravity * height
Here's how to calculate it step-by-step:
Step 1: Determine the mass of the object.
Given that the mass is 5kg, we can use this value.
Mass (m) = 5kg
Step 2: Identify the height.
The object is thrown to a height of 100m, so we use this value.
Height (h) = 100m
Step 3: Use the formula for potential energy.
Potential energy (PE) = mass * acceleration due to gravity * height
Acceleration due to gravity (g) is approximately 9.8 m/s^2.
Potential energy (PE) = 5kg * 9.8 m/s^2 * 100m
Step 4: Calculate the potential energy.
Potential energy (PE) = 4900 Joules
Therefore, the potential energy of the object at the maximum height is 4900 Joules.
To determine the potential energy at the maximum height, we can use the formula for gravitational potential energy:
Potential energy (PE) = mass (m) x acceleration due to gravity (g) x height (h)
First, let's find the acceleration due to gravity, which is approximately 9.8 m/s^2.
PE = 5 kg x 9.8 m/s^2 x 100 m
= 4900 kg*m^2/s^2
Therefore, the potential energy of the body at the maximum height is 4900 Joules (J).
In this calculation, we used the formula for potential energy, which is the product of mass, acceleration due to gravity, and height. The acceleration due to gravity is assumed to be a constant value of 9.8 m/s^2 near the Earth's surface. By substituting the given values into the equation, we calculated the potential energy at the maximum height.
