Questions & Step-by-Step Solutions

In a frictionless environment, if a 5 kg block is pushed with a force of 20 N, what will be its acceleration?
Correct Answer: 4 m/s²
  • 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: Use the formula F = ma, where F is the force, m is the mass, and a is the acceleration.
  • Step 4: Substitute the known values into the formula: 20 N = 5 kg * a.
  • Step 5: To find acceleration (a), rearrange the formula to a = F / m.
  • Step 6: Substitute the values: a = 20 N / 5 kg.
  • Step 7: Calculate the acceleration: a = 4 m/s².
