A ball is thrown with enough speed straight up so that it is in the air several seconds What is its velocity 2s before it reaches its highest point?
All the time the ball is in the air, its acceleration is 9.8 meters (32.2 feet) per second2 downward. In other words ...Every second it's in the air, its downward speed is that much faster than it was one second earlier.When it reaches its highest point, its speed will be zero.Two seconds earlier, its DOWNWARD speed was that much LESS than it is at the top. In other words ...Its UPWARD speed was that much MORE than it is now.So 2 seconds ago, its upward speed was (2 x 9.8) = 19.6 meters per second / (2 x 32.2) = 64.4 feet per second.
An object is dropped and falls to the ground with acceleration of g if its thrown upward at an angle its acceleration would be 0 larger than g g upward g downward or none of the above?
The acceleration of the object would still be g downward, regardless of the angle at which it is thrown upward. The acceleration due to gravity always acts in the downward direction towards the center of the Earth. The only difference would be the horizontal component of the velocity due to the initial angle of the throw.
A ball is thrown upward from the ground with a speed of 36.0 ms At what time after being thrown does the ball have a velocity of zero?
A ball that isn't being held up by anything will accelerate vertically because of the influence of gravity. It's rate of acceleration will be 9.78 meters per second2, directed downward, meaning that each second, its speed in the downward direction will be 9.78 meters per second faster than it was 1 second earlier. When this particular ball is released, its downward speed is negative 36 meters per second. How many times (seconds) does gravity need to increase its downward speed by 9.78 m/s in order to increase its downward speed to zero ? (36 / 9.78) = 3.681 seconds (rounded). That's when the negative downward speed has increased to zero, and becomes a positive downward speed. So it's also the peak of the toss.
What will be the change in velocity for a 10 gram object dropped from the roof of a 20 Meter building if it takes 2 seconds to reach the ground?
Assuming the object is in free fall, the change in velocity will be approximately 19.6 m/s downward. This is calculated using the formula v = at, where acceleration due to gravity is approximately 9.8 m/s^2 and time is 2 seconds.
What is the speed of a ball that has dropped from a 100 m tall building when it reaches the ground in 4.5 seconds?
The speed of the ball when it reaches the ground can be calculated using the formula: speed = acceleration due to gravity x time taken. Given that the acceleration due to gravity is approximately 9.81 m/s^2, multiplying it by the time taken (4.5 seconds) gives a speed of approximately 44.145 m/s.
What is the acceleration of falling body at 0.5 seconds?
acceleration of a falling body is 9.8m/s*s and its direction is vertically downward.

What is the duration of Building a Building?
The duration of Building a Building is 420.0 seconds.
What is the time the sunlight reaches the earth?
8 seconds
If the ball leaves his foot from a height of 4 ft write an equation for the vertical height s (in ft) of the ball t seconds after being kicked?
The answer depends on the direction (upward, horizontal, or downward) in which the ball leaves his foot.
What is the duration of Building Bombs?
The duration of Building Bombs is 3240.0 seconds.
What is the average velocity between 0 and 3 seconds?
The average velocity has two parts to it: The average speed and the average direction. The average speed is: (the distance you travel between 0 and 3 seconds) divided by (3). The average direction is: the direction from (the place where you started at 0 seconds) to (the place where you finished at 3 seconds).
Who is the most popular out of one direction and 5 seconds of summer?
Statistically One Direction :)
