Item is dropped off a cliff Gravity immediately grabs hold of it at 9.8 meters per second squard Impact is 9.36 seconds How high is the cliff in meters Assume no air resistance?
Yankeepride
Using the formula s = ut + 1/2at2, where s is the distance travelled, u is the initial velocity, a is the acceleration and t is the time , then :-
s = 0 + [1/2 x 9.8 x (9.36)2] = 429.29 meters (2dp)
The cliff is 429.29 meters high.

What is the relationship of speed and acceleration due to gravity?
-- Acceleration of gravity, on or near Earth, is 9.8 meters ( 32.2 feet) per second2.-- Speed, neglecting the effects of air resistance, is9.8 meters (32.2 feet) per secondmultiplied by(number of seconds since the object was dropped)regardless of the mass, weight, or size of the object.
Suppose a rock is dropped off a cliff with an initial speed of 0 ms What is the rocks speed after 3 seconds in ms if it encounters no air resistance?
The acceleration of gravity is 9.8 m/s2Speed after 3 sec = (9.8 x 3) = 29.4 m/s
Suppose a rock is dropped off a cliff with an initial speed of 0 What is the rock's speed after 5 seconds in if it encounters no air resistance?

How many seconds will it take for an egg dropped from the top of a 363 foot tall building to hit the ground?
Ignoring air resistance . . .H = 1/2 G t2t = sqrt(2H/G) = sqrt(2 x 363 / 32.2) = 4.75 seconds (rounded)
If A ball is dropped from a rooftop what is the ball's velocity after 3 seconds?
gravity = 9.8 m/s2 , 3 x 9.8 = 29.4 m/s (excluding air resistance)
A ball is dropped from the top of an 80m building will the ball hit the round in 4 sec?
Yes.Neglecting air resistance, and using 9.8 m/s2 for the acceleration of gravity,80 meters works out to 4.041 seconds (rounded).

What is the acceleration of an object that has fallen for 6 seconds?
Ignoring air resistance, it's [ 9.8 meters per second2 ].Same as it was as soon as it was dropped, and same as it will be after another 42 seconds.Acceleration of gravity is constant . . . [ 9.8 meters per second2 ] until the cows come home, and even after.
If the same shoe were dropped from a height of 40m how many seconds would it take it to hit the floor?
Gravity = 9.8 meters per second
How long would it take to fall 167 feet?
Surely you're aware that a falling object accelerates under the influence of gravity. That acceleration manifests itself in the form of steadily-increasing speed, so the time required to fall 186 feet depends on how long it has already been falling. -- Immediately after it's dropped, the object falls the first 186 feet in 3.399 seconds. -- It falls the NEXT 186 feet in 1.408 seconds. -- It falls the next 186 feet in 1.08 seconds. -- It falls the next 186 feet in 0.911 second. -- It falls the next 186 feet in 0.802 second. . . etc.
How long in seconds does it take to hit the ground after a ball is dropped from a height of h70 m?
neglecting air resistance, distance = 1/2 gt^2 where g = acceleration of gravity = 9./8 m/sec/sec 70 = 1/2 (9.8) t^2 14.28 = t^2 t = square root 14.28 = 3.78 seconds
A tilapia is dropped by a hovering eagle how far will the fish fall in 2 seconds before the birds?
d=1/2 a t^2 d=1/2 9.8 2^2 d=2*9.8 d=19.6 9.8 is the force of gravity this assumes no air resistance
