Amotorcycle is following a car that is traveling at constant speed on a straight highway. initially, the car and the motorcycle are both traveling at the same speed of 18.0 m/s, and the distance between them is 53.0 m. after t1 = 5.00 s, the motorcycle starts to accelerate at a rate of 4.00 m/s^2. the motorcycle catches up with the car at some time t2. how long does it take from the moment when the motorcycle starts to accelerate until it catches up with the car? in other words, find t2 minus t1. how far does the motorcycle travel from the moment it starts to accelerate (at time t1) until it catches up with the car (at time t2)?

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.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
