Question

QUESTION 1 You and your brother are pushing a car with a dead battery with forces of 43 N and 49 N in the same direction. What is the net force applied to the car? QUESTION 2 Bob pushes on a crate with a force of 612 N. If the force of friction on the crate is 296 N, what is the net force on the crate? QUESTION 3 How much force is needed to accelerate a truck with a mass of 1,499 kg at a rate of 2 m/s QUESTION 4 What is the mass of an object that requires a force of 92 N to accelerate at a rate of 3.1 m/s? QUESTION 5 What is the acceleration of a 3 ball that is hit with a force of 10 N?

Explanation / Answer

Question 1.

If we both are pushing the car in the same direction then the net force will be the addition of both the forces.

F=43+49

F=92N

Question 2.

Friction will oppose the applied force so,

F=612-296

F=316N

Question 3

We know that F=ma

F=1449*2

F=2998N

Question 4

Again using F=ma

m=92/3.1

m=29.67kg
