Q
Q: A 15 kg object is at rest on a table. What is the force exerted by the table on the object?
Solution:
The normal force equals the weight of the object: 15 kg * 10 m/s² = 150 N.
Steps: 6
Show Steps
Step 1: Identify the mass of the object, which is 15 kg.
Step 2: Understand that the object is at rest on the table, meaning the forces acting on it are balanced.
Step 3: Calculate the weight of the object using the formula: weight = mass * gravity.
Step 4: Use the value of gravity, which is approximately 10 m/s².
Step 5: Multiply the mass (15 kg) by the gravity (10 m/s²): 15 kg * 10 m/s² = 150 N.
Step 6: Conclude that the force exerted by the table on the object (normal force) is equal to the weight of the object, which is 150 N.
