A 10N (weight) falling object encounters 8.0N of air resistance.
What is the mass of the object?
What is the acceleration?
We can start by using the formula for net force:
Net force = mass x acceleration
In this case, the net force is the weight minus the air resistance:
Net force = 10 N - 8.0 N = 2.0 N
We know that the acceleration due to gravity is approximately 9.81 m/s^2. Therefore, we can calculate the mass of the object as:
mass = net force / acceleration
mass = 2.0 N / 9.81 m/s^2 = 0.204 kg (to three significant figures)
So the mass of the object is 0.204 kg.
To find the acceleration, we can rearrange the formula to solve for acceleration:
acceleration = net force / mass
acceleration = 2.0 N / 0.204 kg = 9.80 m/s^2 (to three significant figures)
Therefore, the acceleration of the object is 9.80 m/s^2.

Solve & Explain Steps Please. 6. Consider the problem of a free falling object with mass M. Assume that only gravity and air resistance act upon the object. (a) As a first model, let us suppose that the air resistance is proportional to the velocity v(t) of the object. Newton's second law of motion gives the DE M)go),20 More exactly, this is a first order linear DE with constant coefficients: Mw,(t) + ku(t) = Mg , t 2). Suppose that...
A falling skydiver has a mass of 102 kg. What is the magnitude of the skydiver's acceleration when the upward force of air resistance has a magnitude that is equal to one-fourth of his weight?

Select the true statement(s): (2 points) In vacuum, all objects, no matter the mass, should theoretically fall with the same acceleration The weight of an object on Earth is same as the weight it would have on the moon. The weight would vary slightly at different locations on the earth's surface becauseg varies slightly from place to place on the earth. * * . The gravitational acceleration g 4.9 N/k 2. Select...
5. In certain circumstances, we can model the velocity of a falling mass subject to air resistance as - dv m7 = mg – kv?, where v (t) is the velocity of the object, m is the mass of the object, g is acceleration due to gravity, and k is a constant of proportionality. Assume the positive direction is downward. (a) Solve this equation subect to the initial condition v (0) = vo. (b) What is the terminal velocity of...

In the absence of air resistance as an object travels through the air, its horizontal component (Vx) of the velocity vector has what acceleration?
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...
