Q
Q: A block of mass 2 kg is pushed along a frictionless surface by a constant force of 10 N. What is the work done by the force when the block moves 5 m?
Solution: Work done = Force × Distance = 10 N × 5 m = 50 J.
Steps: 6
Step 1: Identify the force applied to the block, which is 10 N.
Step 2: Identify the distance the block moves, which is 5 m.
Step 3: Use the formula for work done, which is Work = Force × Distance.
Step 4: Substitute the values into the formula: Work = 10 N × 5 m.
Step 5: Calculate the result: 10 N × 5 m = 50 J.
Step 6: Conclude that the work done by the force is 50 Joules.
