## Newton's Laws

(1) Consider the following forces applied to a body:

What is the resulting force applied?

*Module: 5N-3N = 2N*

*Direction and Direction: Same as Force Majeure (5N)*

(2) A force of 50 N is applied to a resting body of 100 kg mass. Since this is the only force acting on the body, how fast is it reached after 10 seconds of force application?

*Knowing the acceleration of the body we can calculate its velocity:*

(3) What is the mass of a body that, from rest, reaches a speed of 12m / s in 20s? Knowing that the force applied to it has a modulus equal to 30N.

*Knowing the acceleration of the body:*

## Strength Weight

(1) What is the minimum force that must be done to lift a car with 800kg mass?

*The force must be greater than or equal to the weight force, then:*

(2) What is the mass of a body weighing 12000kgf?
