Q
Q: A block of mass 5 kg is placed on a frictionless surface and is pushed with a force of 20 N. What is the acceleration of the block?
Solution:
Using Newton's second law, F = ma, we have a = F/m = 20 N / 5 kg = 4 m/s².
Steps: 6
Show Steps
Step 1: Identify the mass of the block, which is 5 kg.
Step 2: Identify the force applied to the block, which is 20 N.
Step 3: Recall Newton's second law of motion, which states that Force (F) equals mass (m) times acceleration (a), or F = ma.
Step 4: Rearrange the formula to solve for acceleration (a): a = F/m.
Step 5: Substitute the values into the formula: a = 20 N / 5 kg.
Step 6: Calculate the acceleration: a = 4 m/s².
