What is the height of a tower if a rock dropped from it hits the ground after falling for 2 seconds?
19.6 meters / 64.4 ft
An object with a mass of fifteen kilograms is dropped from a building neglecting friction which is the buildings height?
It's not possible to calculate the answer with the information given.An object with a mass of 15 kg can be dropped from a building of any height.
What would 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 Hint acceleration due to gravity is 9.8 ms²?
Acceleration = (change in velocity) / (time for the change)9.8 = (change in velocity) / (2 seconds)9.8 x 2 = change in velocity = 19.6 meters per second .Hint: The mass of the object and the height of the building are there just tothrow you off balance. You don't need either of them to answer the question.
Which will hit the ground first a ball thrown horizontally at 2 meters per second off a building 20 m high or a ball dropped by a hand at the same height?
They should reach the ground together, since their initial vertical speed is the same, namely zero.
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.

A basketball is dropped from a tall building and hits the pavement 30 seconds later What was the speed of the ball as it hit the pavement?
.. You need the height of the building to figure it out..?
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 if a ball is dropped off the roof of a tall building if the ball reaches the ground in 3 seconds how tall is the building?
The vertical distance covered by a free falling object is given by the formula: S= ut+0.5at^2, where S is the distance covered (height of the building), u is the initial velocity (for this case it is 0 since the body is released from rest), t is the time taken for the object to hit the ground (it has taken 5 seconds) and a is the acceleration due to gravitational pull (assumed to be 9.8ms^2). Therefore, the height of the building is given by (0x5 +0.5x9.8 x25) which is 122.5m.
