Q
Q: A 5 kg block is resting on a horizontal surface. What is the normal force acting on the block?
Solution:
The normal force equals the weight of the block, which is mass times gravity: 5 kg * 9.8 m/s² = 49 N.
Steps: 6
Show Steps
Step 1: Identify the mass of the block, which is given as 5 kg.
Step 2: Understand that the normal force is the force that supports the weight of the block on a surface.
Step 3: Recall the formula to calculate weight, which is weight = mass × gravity.
Step 4: Use the value of gravity, which is approximately 9.8 m/s².
Step 5: Calculate the weight of the block: 5 kg × 9.8 m/s² = 49 N.
Step 6: Conclude that the normal force acting on the block is equal to its weight, which is 49 N.
