VERY IMPORTANT FOR AN ESSAY ASSIGNMENT. PLEASE HELP ASAP! THANK U VERYYYYY MUCH!

1. What force is needed to give a mass of 25 kg an acceleration of 20m/s squared?

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?

b) what is the mass of an object that weighs 490N?

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

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