A pebble is dropped from the top of a 144-foot building. The height of the pebble h after t seconds is given by the equation h-16t2 plus 144h and minus16t2 plus 144 . How long after the pebble is drop?
A pebble is dropped from the top of a 144-foot building. The height of the pebble h after t seconds is given by the equation h=−16t2+144 . How long after the pebble is dropped will it hit the ground?Interpretationa) Which variable represents the height of the pebble, and in what units?b) Which variable represents the time in the air, and in what units?c) What equation relates the height of the object to its time in the air?d) What type of equation is this?e) What are you asked to determine?
What is 1 penny in a decimal form?
i penny is 1 out of 100 cents, therefore it is .01
If you drop a coin and a leaf from the same height which will ht the ground first?
1) it depends how high up you are 2)which coin (e.g. 1p 2p 10p 20p 50p £1 and so on) 3)it depends which one you drop first as you can see there are many answers to this question but i would say the coin
Drop caps look better if you increase of the first line?
Drop caps generally look better if you decrease the line height of the first letter.
Would a 84 inch round plastic table cloth fit 60 inch round table?
84 inches round tablecloth gives a drop of 12 inches for 60 inch round table. If you want the drop up to the ground,120 inches round tablecloth is perfect fit. (above tablecloth sizes is applicable only to the std height table 29 inches)
You drop a penny from a height of 16 feet After how many seconds does the penny land on the ground?
1 second, since all objects fall at 16 feet per second.
If you drop a tennis ball how long will it take to touch the ground?
It depends on what height you drop it from.
What will happen to the stone once it hit the ground from the hill?
It is quite obvious, it will just hit the ground. The force depending on the height you dropped it from. For example: If you drop it from a high height it may shatter or it may land with more pressure. If you drop it from a low height it will simply drop with hardly any pressure.
What will hit the ground first a pencil or penny?
There are many factors that can affect the time for these objects to drop. The height at which each object is dropped is a factor since the height is proportional to time. if the height at which these objects are dropped are the same, then the time for them to drop to the floor is the same. Since the acceleration due to gravity at sea level is 9.81 m/s^2 for all objects no matter the mass, both objects will accelerate at the same rate which means they will reach the floor at the same rate. All in all, both the pencil and the penny will hit the ground at the same time.
If you drop a penny and a text book at the sametime. which one will hit the ground first?
If a penny and a text book were dropped in a vacuum then they will both hit the ground at the same time. This refers to Newton's laws. If they are dropped at the same time on earth then the text book would hit the ground first.
Drop a penny from a tower and it takes 4.82 seconds to hit the ground. How tall is the tower?
Neglecting air resistance ...X = 1/2 G t2 = 1/2 (9.8) (4.82)2 = (4.9) (23.2324) = 113.84 meters (373.5 ft) (rounded)
If you drop a penny and a quarter from the same position at the same time which one will hit the floor first?
Theoretically each will hit the ground at the exact same time. Practically, however, the distance from the drop position to the ground is a very impotant factor. If you drop both at a relatively short distance (say 5 feet) they will effectually hit at the same time if they encounter no wind resistance. If you drop them at a much higher distance (say 100 feet) the quarter will hit the ground before the penny. The reason being is resistance to the flat surface of the penny verses the quarter. Since the penny is much lighter than the quarter (a penny weighs 2.5 grams and a quarter weighs 5.67 grams) it will be affected to a greater degree by wind resistance that the much heavier quarter. You can liken it as to a feather being dropped. The feather will flip and twist and float as it slowly drifts down to the ground. The quarter being heavier will drop less reactivly and have a much straighter decent and therefore hit the ground sooner.
How do you measure height by dropping an object?
-- Take a heavy object and a stopwatch. -- Start the timer as you drop the object from the unknown height. -- Stop the timer when the object hits the ground. -- Read the time off the watch, in seconds. Square it. (Multiply it by itself.) -- Multiply that result by 16.1 . -- Now you have the distance the object fell, in feet.
When you drop a tennis ball to the ground why doesnt it return to its initial height?
because it wants to be low enough to give a blowy
Can you use time to measure height?
Yes. Drop a rock from the top of the height, and carefully measure the time it takes to hit the ground.If ' T ' is the number of seconds it falls, then the height is4.9 T2 metersor16.1 T2 feet.
How fast does a tennis ball lose its bounce?
depends on what height you drop it like 5 inches its 2 seconds
What is drop height?
The height from which the manufacturer says you can drop the drive with out making it unusable.
