Question

A block of mass 5 kg is placed on a frictionless surface and a force of 20 N is applied horizontally. What is the acceleration of the block?

• A. 4 m/s\(^2\)
• B. 2 m/s\(^2\)
• C. 5 m/s\(^2\)
• D. 10 m/s\(^2\)

Hint:

For frictionless surfaces, use Newton's second law directly to find acceleration.
