A force of acts on a cart of mass on a frictionless horizontal floor. What is the acceleration produced?

Answer and explanation

Correct answer: D. 5 m/s^2

  1. Step 1: Apply Newton's second law of motion: .
  2. Step 2: Solve for acceleration: .
Answer
5 m/s^2.
Why not the others: '4 m/s^2' divides by ; '80 m/s^2' multiplies force by mass (); '0.2 m/s^2' inverts the division ().
