Understanding the Concepts
* Work: Work is done when a force causes an object to move a certain distance. The formula for work is:
* Work (W) = Force (F) × Distance (d)
* Force due to gravity (Weight): The force acting on the object due to gravity is its weight, which is calculated by:
* Weight (F) = Mass (m) × Acceleration due to gravity (g)
* (Where g is approximately 9.8 m/s²)
Calculations
1. Calculate the weight of the object:
* F = (3.88 kg) × (9.8 m/s²)
* F ≈ 38.02 N (Newtons)
2. Calculate the work done:
* W = (38.02 N) × (2.45 m)
* W ≈ 93.15 J (Joules)
Answer: The work accomplished in lifting the object is approximately 93.15 Joules.
