Question

a net force 28N is acting on a falling object. It experiences an air resistance of 8.5 N. Accekeration due to gravity is 9.81 m/s2 what is the mass

science physics

Answer 1

Answer #1

Net force Fnet = 28 N;

AIR resistance Fa = 8.5 N:

let mass of the object is m kg;

then force of gravity F = mg;

Fnet = gravity force - air resistance;

28 = F - Fa;

28 = mg - 8.5;

mg = 36.5;

m = 3.72 kg

A package of mass 50 kg is dropped from a helicopter and experiences a drag force of 120 N due to air resistance. Find the resultant force and use it to calculate the acceleration of the package during the fall. Take the acceleration due to gravity as g = 9.81 m s-2 and give your answer in m s-2 to 1 decimal place. Answer: Answer m s-2
When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil)

When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil), it accelerates due to the force of gravity. If gravity were the only force acting on the object, then all objects-elephants and feathers alike would fall at the same rate. But gravity is not the only force present. Moving objects also experience resistance or friction from the surrounding medium; it would be air resistance for...
