Newton's Second Law: F = ma — Homework
Always combine forces into a single net force before applying F=ma.
- 1.A 1500 kg car experiences a net force of 4500 N. Find its acceleration.
- 2.A 2 kg block is pushed with 18 N while friction resists with 4 N. Find its acceleration.
- 3.Find the weight of a 45 kg object on Earth.
- 4.A 60 kg astronaut has a weight of about 588 N on Earth but only about 98 N on the Moon. Explain why the astronaut's MASS is still 60 kg in both places.
- 5.Describe a real example of Newton's second law from sports or driving, naming the force, the mass, and the resulting acceleration in words.
