Kieran pushes a box with a force of 35 N. It accelerates at 5 m/s2. What is the first step that is needed to calculate the mass of the box? Identify the formula to calculate velocity.
Identify the formula to calculate force.
Identify the formula to calculate acceleration.
Identify the formula to calculate weight.

f=ma

mass of box =7kg

Explanation:

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

the components of a vector are the parts of the vectors that are to each other.
