Young jeffrey is bored, and decides to throw some things out of the window for fun. but since he is also very curious, he decides to do so in a controlled way, jeffrey takes a rock, his tennis ball, and one of his father's golf balls and sets them on the sill of an open window. then he uses a flat board to carefully push them all out of the window at the same time. the 2nd story window is 12.0 feet above the ground, and all three objects hit the ground just 0.500 feet away from the base of the house at the same time, 0.863 seconds after they're dropped. the rock hits with a thud and stays put, but the other two objects bounce. after another 0.647 seconds, the tennis ball reaches a maximum height of 6.75 feet, while the golf ball is 9.45 feet off the ground and still rising. both have travelled an additional 0.375 feet horizontally calculate the magnitude of the average velocity of each object during these 1.51 seconds. which object has the largest instantaneous velocity at the end of this time period?

come closer and become far apart and become steam/gas

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.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

amplitude

hope this
