Think about what is causing these objects to accelerate.

That’s a force: a push or pull

What force is required to accelerate an object having a mass of 3 kg at 5 m/s2?

A dog with a mass of 42 kg is resting on a cat.

What force does it exert on the cat?

A child is accelerated at 8 m/s2. His mass is 33 kg. With what force was his body thrown?

Mrs. Lonnberg throws away a box of trash. She uses a force of 30 N and the box accelerates at 4 m/s2.

What is the mass of the box?

Mrs. Lonnberg kicks a 7 kg cat with a force of 49 N.

What is the cat’s acceleration?

A giant soccer ball falls onto a car. The force of the collision is 9,200 N. What is the mass of the ball?
