How do you answer this physics question?
A ball is thrown vertically upward with an initial speed of 20m/s. Two second later, a stone is thrown vertically (from the same initial height as the ball) with an initial speed of 24m/s. At what height above the release point will the ball and stone pass each other?
A rock is thrown vertically into the air At the very top of its trajectory the net force on it is?
The net force is gravity. The speed is zero.
What relationship exists between the initial velocity and the maximum height reached by an object thrown upward?
Ignoring air resistance, I get this formula:Maximum height of a vertically-launched object = 1.5 square of initial speed/GI could be wrong. In that case, the unused portion of my fee will be cheerfully refunded.
What happens to the speed of an object when it is thrown up in the air and when it comes back down?
an object thrown into the air will slow down as it ascends higher into the air until it stops ascending and the speed of the object increases as it falls until it reaches its terminal velocity in air. As an object passes through air, it encounters air resistance which slows down an object moving freely through air. An object will be moving at a slower speed when it hits the ground than it did when it was thrown into the air due to this air resistance.
Can an object have a speed of 0 while it has an acceleration that is not 0?
Yes. Acceleration is independent of speed. A perfect example of an object with zero speed but nonzero acceleration is an object at the apex of being thrown upward. The entire time it is in the air it is accelerating downward. At its maximum height its speed is zero.

If an object can be thrown up to 600feet what is the estimated speed?
well in order to calculate the speed of the object at the start point you need to know: # mass/weight of the object # the air resistance # the angle # the form of the object

Does uniform speed properly characterize the motion of a heavy object thrown violently downward from a tall building?
No. Regardless of its initial speed, the object still experiences downward acceleration at the rate of 'G'.
An object that is thrown vertically upward will return to its original position with the same speed as it had initially if air resistance is negligible if air resistance is appreciable?
As an object rises WITH air resistance, the acceleration is larger in size than g, because both gravity and air resistance will be causing a downward acceleration. As the object FALLS with air resistance, the acceleration will be smaller in size than g, because gravity and resistance will be opposing each other. Because of the smaller acceleration being applied over the same distance, the return speed will be slower than the launch speed.
If you drop an object it will accelerate downward at a rate of 9.8 meters per second squared if you instead throw it downwards its acceleration will be greater or less 9.8 meters per second?
Whether the object is dropped, thrown downwards, thrown upwards, or thrown horizontally, its downward acceleration is the same 9.8 meters per second2. If it's thrown downwards, however, its speed at any instant is greater than the speed at the same instant would be if it had only been dropped, since it has some speed before the acceleration begins.
A ball Thrown vertically from the ground level caught 3.0 second latter when it is at highest point by a person on a balcony which is 14 m above the ground determine the initial speed of the ball?
42
Does different speed of two objects effect the time it takes to reach the ground?
If thrown horizontal from same height the faster object will travel farther horizontally, but time to fall is the same. If thrown straight up, the faster object will take longer to fall
When was RADAR first used for baseball?
Radar was first used to measure the speed of a moving object in 1935. By 1938, they were used to measure the speed of a fastball thrown by Bob Feller.
