Problem 2 : A block of mass 2 kg is lifted vertically through a distance of 10 meters. Calculate the work done in lifting the block, and express it in joules.
Solution :
The work done (W) in lifting an object against gravity is given by the formula:
- W = Work done (in joules)
- m = Mass of the object (in kilograms)
- g = Acceleration due to gravity (approximately 9.81 m/s²)
- h = Height or vertical distance (in meters)
Substituting the values:
