Homework Answers
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...

1.There is a falling object, whose mass is A [kg] and experiences a force (its own weight) equal numerically to A times 9.81. The object starts from rest and the air causes a retarding force numerically equal to B times its velocity. a)Find general expression for velocity as a function of time, and draw its graph. b)Evaluate velocity for t = C (s) Depending on your value of R choose R A B C 0 6 0.180 4 1 7 ...
