A projectile of mass m = 5kg is thrown upward vertically with a velocity v0 = 9 m/s

a) Starting with Newton's 2nd Law FNet = ma, calculate the time to an accuracy of four decimal places at which the maximum height is reached when no air resistance is present.

b) Starting with Newton's 2nd Law FNet = ma, calculate the time to an accuracy of four decimal places at which the maximum height is reached when considering the following force of air resistance:

Fair = 7.775 x 10-5v

c) Starting with Newton's 2nd Law FNet = ma, calculate the time to an accuracy of four decimal places at which the maximum height is reached when considering the following force of air resistance:

Fair = 0.055v2

A ball of mass m is projected vertically upwards at a velocity v◦. The ball experiences an air resistance force (in addition to gravity) of the form FR = −αv^2 where α > 0 is constant and v is the velocity, and reaches a maximum height h before it returns back to the point of projection. (a) Write down the equations of motion of the ball during its upward and and downward journeys and show that the maximum height reached...

An airplane in flight is subject to an air resistance force proportional to the square of its speed v. But there is an additional resistive force because the airplane has wings. Air flowing over the wings is pushed down and slightly forward, so from Newton's third law the air exerts a force on the wings and airplane that is up and slightly backwardThe upward force is the lift force that keeps the airplane aloft, and the backward force is called induced drag. At...

For his engineering project, Fran¸cois built a model rocket of mass m = 0.55 kg simply by using materials he found lying around the lab and blueprints he found on the internet. The rocket’s propulsion is provided by a special battery-powered fan that is able to provide a constant force |Ffan| = 7.0 N – that is, once it is launched in a specific direction, the direction of the fan’s force does not change. The downside is that the rocket...
