A ball is dropped from the top of a building and hits the ground 3 seconds later. a. what is the height if the building b. with what speed did it hit the ground?
a. 144 feet b. 96 ft/sec.
How far does a rock fall in 9 seconds?
depends on the mass of the stone, the shape of the stone, and the height dropped from. sorry dude.
If a ball is dropped from a height of 100m each time it hits the ground it bounces 3 5ths of the height it fell How far will the ball have traveled in the 5th bounce?
89
A stone was dropped off a cliff and hit the ground with a speed of 96 ft per second what is the height of the cliff?
240 ft
How long does it it take an object of 4 kg to hit the ground considering another object with a mass of 2 kg took 3 seconds to hit the ground?
Assuming they were in a vacuum, if both objects were dropped from th esame height, then both take the same length of time to reach the ground. All masses fall with the same acceleration, reach the same speed in the same period of time, and hit the ground at the same time. Otherwise and if there is an atmosphere or if they are dropped from different heights, you have not presented information; shape and size are the most important factors.
Which has more kinetic energy a ball dropped from a height of 2m or a same ball dropped at 4m which has more kinetic energy just before it hits the ground?
The ball dropped from 4m height has more kinetic energy just before it hits the ground because it has a higher velocity due to falling from a greater height. Kinetic energy is directly proportional to both mass and the square of velocity, so the ball dropped from 4m height will have more kinetic energy than the one dropped from 2m height.

How long will it take an object dropped from a height of 500 feet to hit the ground?
Assuming the object is dropped from rest and neglecting air resistance, it would take approximately 7.0 seconds for the object to hit the ground from a height of 500 feet. This is based on the formula t = sqrt(2h/g), where t is the time, h is the height, and g is the acceleration due to gravity (approximately 32.2 ft/s^2).
Do two objects of the same mass dropped at different height have a different speed?
Yes, two objects of the same mass dropped at different heights will have different speeds when they hit the ground due to the influence of gravity. The object dropped from a higher height will have a higher speed upon impact because it had more time to accelerate while falling.
When will the ball hit the ground if dropped at 443 meters high?
The time it takes for a ball to hit the ground when dropped from a height can be calculated using the equation: t = ā(2h/g), where h is the height (443 meters) and g is the acceleration due to gravity (9.81 m/sĀ²). Solving for t gives a time of approximately 9 seconds.
If a shoe is dropped from a height of 40m what is its speed after falling for two seconds?
Regardless of the height from which it is falling, (neglecting air resistance) it's speed will be 19.62 metres per second. (Acceleration from gravity is 9.81 metres per second squared, so after 1 second it is moving at 9.81 metres per second and after 2 seconds it is moving at 19.62 metres per second.
What are examples of free fall?
An object dropped from a height without any initial velocity, a skydiver falling towards the ground before deploying their parachute, and a rock falling off a cliff are all examples of free fall.
What is an example of an free fall?
A rock that is dropped, and a apple falling from a tree.Hold a ball in your hand, stretch out your arm, and drop the ball. As it is moving towards the ground, it is in free fall.
A marble a textbook and a flaming stick are simultaneously dropped from a height of 10 feet if air resistance upon the falling objects is small enough that it can be neglected which will hit first?
All objects dropped from the same height will hit the ground at the same time, regardless of their mass or shape, as long as air resistance is negligible. Thus, the marble, textbook, and flaming stick will hit the ground simultaneously.
When You Drop An Object From A Certain Height It Takes Time T To Reach The Ground With No Air Resistance. If You Dropped It From Three Times That Height How Long Would It Take To Reach The Ground?
When an object is dropped from a certain height, the time it takes to reach the ground is independent of the height (assuming no air resistance). Therefore, whether you drop the object from three times the initial height or the original height, it will still take the same time (T) to reach the ground.
If a ball takes 11 seconds to stop if dropped from 1 foot and 25 seconds from 2 feet how many seconds if dropped from 3 feet?
If we assume the time it takes for the ball to stop is directly proportional to the height it is dropped from, we can set up a proportion based on the given information. From the given data, we have the ratio of time to height as 11/1 = 25/2. Therefore, if we continue this ratio, the time it would take to stop if dropped from 3 feet would be 55 seconds.
What is the velocity of a ball that has a 3.03 second hit to the ground?
To calculate the velocity of the ball, we need to know the height from which it was dropped. If the ball was dropped from rest, we can use the formula for free fall motion: velocity = (acceleration due to gravity * time). Assuming the acceleration due to gravity is 9.81 m/s^2, the velocity of the ball hitting the ground after 3.03 seconds would be around 29.7 m/s.
