If we are talking in vaccum then both will have same acceleration.But if there is no vaccum then paper crumbled into a ball will have greater acceleration because air resistance will be less for it.

Why does building foundations have a large horizontal area of contact with the ground?
this is because when the area of contact between the ground and the building increases the pressure exerted by the building will be less for the same force.
When dropped from a building a cricket ball and a football have the same velocity or they hit the ground at same instant which more correct answer?
they hit the ground at same instant
Why is it dangerous to jump of a tall building Explain this in terms of the forces acting on you?
There is no air resistance to keep you from hitting the ground, the density of your body is heavier then the air, causing you to fall quickly into the ground.
If a blonde and brunette fall from a building at the same time who hits the ground first?
The blonde because she fell off a shed by accident
How high is the building if the time it takes for a lead weight dropped from the top of the building to fall the last 1.5 m before hitting the ground is .109s?
That depends on the mass of the lead weight and the time it took to cover the rest of the fall.
A student has two identical sheets of paper He crumples one up into a small ball If he drops the sheet of paper and the ball of paper off a building at the same time which of the following statemen?
~CORRECT ANSWER~ its: The sheet of paper, because it has more surface area.
A student drops a ball from the top of a tall building it takes 2.8 s for the ball to reach the ground?
yes it could,it depends on the size and mass of the ball
If you were to take two identical objects and drop one off a building while at the same time throwing the other out horizontally off the same building which would hit the ground first?
It really depends on a few key factors: wind velocity, and how hard you throw the object horizontally off of the building.

Are the neutral and ground bonded in a sub-panel of an out building?
The neutral and ground are only bonded in a sub-panel of an out building if the code requires a buried ground rod or plate at this location.
Building Foundation and sub-structure what is it?
building foundation is the base of any building which receive load from the building, resist it and transfer it to the subsoil. substructure is the structure below the ground floor bed including the ground floor bed. substructure composes of foundation, basement and ground floor bed.
How can the type of ground beneath a building affect the building's response to seismic?
It can affect the strength, durability, or the sturdiness of the building. If the ground beneath it is sand, It is more than likely to fall during an earthquake or something. Sand is a horrible foundation for a building. Loose soil can also affect the building in the same way, making it slide or sink into the ground.
What do you call the support of a building that is usually constructed below ground level?
The support of a building that's usually constructed below ground level is called a basement. Sometimes it is also the "Base" contruction of a building.
What is ground area?
Ground area is defined as the area a building occupies at ground level. The area is computed based on the exterior dimensions of the ground.
How does the base isolation system work?
This is when a building is separated from the ground that it is built on by large plates. One plate is secured to the ground and the other is secured to the bottom of the building. These plates move a certain distance when the ground shakes.
What is foundation in civil engineering?
Foundation is the sub-structure of a building structure that transfers the entire weight of the building and its loads onto the ground strata below ground level.
