What is the potential energy of 5 kg apple that is sitting on a 1.5 m high tree branch
The potential energy of the 5 kg apple can be calculated using the formula P.E. = mgh, where m is the mass of the object (in kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height from which the object is falling (in meters).
P.E. = 5 kg x 9.81 m/s^2 x 1.5 m
P.E. = 73.575 J
Therefore, the potential energy of the 5 kg apple sitting on a 1.5 m high tree branch is 73.575 J.
What is the potential energy of a puppy that weighs 18 N sitting in a high chair 2m high
The potential energy of the puppy can be calculated using the formula P.E. = mgh, where m is the mass of the object (in kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height from which the object is falling (in meters).
First, we need to convert the weight of the puppy from Newtons to kilograms.
Weight = Mass x Acceleration due to gravity
18 N = m x 9.81 m/s^2
m = 18 N / 9.81 m/s^2 ≈ 1.835 kg
Now we can calculate the potential energy:
P.E. = 1.835 kg x 9.81 m/s^2 x 2 m
P.E. = 35.861 J
Therefore, the potential energy of the 1.835 kg puppy sitting in a high chair 2 m high is 35.861 J.
A box weighing 30N is pushed a distance of 5 meters. How much work was done
Work (W) is defined as force (F) multiplied by distance (d) in the direction of the force, so we can use the formula:
W = F x d
In this case, the force is the weight of the box, which is 30N, and the distance it is pushed is 5 meters. Therefore:
W = 30 N x 5 m = 150 J
Therefore, the work done on the box is 150 joules (J).
What is the potential energy of a puppy that weighs 18 N sitting in a high chair 2m high
g cancels
m g h = F h = 18 Newtons * 2 meters = 36 Joules
That is correct. The potential energy of the puppy is 36 J.
A box weighing 30N is pushed a distance of 5 meters. How much work was done
NONE !!! = 0.00 The force is perpendicular to the motion. Friction is not mentioned.
As an AI language model, I must apologize for my previous response. You are correct in that we cannot determine the work done without additional information such as the angle and direction of the force, the presence of friction, and whether the motion is in a straight line or a curve. Without knowing these additional details, we cannot accurately calculate work done on the object.
To calculate the potential energy of an object, you need to know its mass and the height at which it is situated. The formula for potential energy is:
Potential Energy = mass × acceleration due to gravity × height
In this case, the mass of the apple is given as 5 kg, the height is 1.5 m, and the acceleration due to gravity is approximately 9.8 m/s^2.
So, the potential energy can be calculated as:
Potential Energy = 5 kg × 9.8 m/s^2 × 1.5 m
Now, let's solve this equation step by step:
Step 1: Multiply the mass and acceleration due to gravity:
5 kg × 9.8 m/s^2 = 49 N
Step 2: Multiply the result from Step 1 by the height:
49 N × 1.5 m = 73.5 joules
Therefore, the potential energy of the 5 kg apple sitting on a 1.5 m high tree branch is 73.5 joules.
