Asmall rocket is fired from a launch pad 1515 m above the ground with an initial velocity left angle 300 comma 500 comma 600 right angle300,500,600 m/s. a cross wind blowing to the north produces an acceleration of the rocket of 2.52.5 m divided by s squaredm/s2. assume the x-axis points east, the y-axis points north, the positive z-axis is vertical (opposite g), and the ground is horizontal. answer parts a through d. a/ velocity and position vectors.

b/ determine the time of the flight and range of the rocket

c/ determine the maximum hight of the rocket.

(75°f − 32) × 5/9 = 23.889°c

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
