2. A force of 6N acts upon a 2-kg mass. What is the acceleration of the masS?

3. It takes a force of 50N to give a body an acceleration of 10m/s squared. What is the mass of the body?

4. a) what is the weight of a 10-kg piece of iron?

Try using Newton's second law: F = m a

m is the mass and a is the acceleration. The force will be in Newtons.
