Question

An object of mass 30 kg is falling in air and experiences a force dur to air resistance of 50 newtons. What's the acceleration of the object?

Answer 1

Answer:

Newton's second law states that the acceleration an object experiences due to a given force is inversely proportional to its mass, that is --

a=Fm

If the acceleration is 10m/s2 and the object's mass is 2kg , we can use Newton's second law to find that:

10m/s2=F2kg

F=20kg m/s2 , or 20N .

Answer 2

Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. ... The object experiences an acceleration due to gravity g: w = mg.
