A ball is thrown straight up from the edge of the roof of a buildinga second ball is dropped from 1sec later ignore air resistance?

... and what is the question? The second ball should arrive at the floor a second after the first, both should have the same speed.

A rock is dropped from rest and falls for 3 seconds what is the acceleration?
The acceleration due to the earths gravitational field at the surface is on average about 9.8 m/s^2, or 9.8 meters per second per second. This means that every second you fall go 9.8 m/s faster. So if we ignore air-resistance we find that a rock dropped from rest will have a speed of 3s * 9.8 m/s^2 = 29,4 m/s.
How do you round 1.632 to one decimal place?
When rounding up if a number is 5 or more you add one to the next column. If a number is 4 or less you just ignore it. So 1.632 becomes 1.63 (2 is less than 5 so it is dropped). This then becomes 1.6 (3 is dropped because it is less than 5).
How long would it take a water balloon to drop 200 feet?
if you ignore air resistance, it would take about 3.5 seconds; at ttat point where it hits the ground it is traveling at 75 mph. Because of the air drag, it may take a bit longer to hit the ground.
How many ways can 5 people stand in a strait line if Jessie is always third?
Not sure what a strait line is! Five people can stand in a straight line, with Jessie third in 24 ways if you ignore left-to-right and right-to-left "reflections".
A cannonball is fired straight up at 50 ms Neglecting air resistance when it returns to its starting point its speed is?
50m/s. The kinetic energy (movement energy) of the ball when it leaves the gun is gradually converted into gravitational potential energy as it moves up and slows down. Eventually it reaches its highest point and stops. It has zero kinetic energy, all the energy has been converted into gravitational potential. The ball then starts to fall under gravity. The gravitational potential energy is converted back into kinetic energy. No energy is lost so the ball arrives back where it started with the same kinetic energy it left with or to put it another way at the same speed it left. If you do not ignore air resistance it arrives back a bit slower and the physics gets much much more complicated..........
F a tennis ball and a bowling ball are dropped from a 5 story building which one would land first?
if we ignore wind resistance they will land at the same time.
Does the horizontal motion affect the vertical motion of a projectile?
Not if you can ignore air resistance, it doesn't.
If two bodies of different mass fall from same height will they reach at the same time?
Yes - but only if you can ignore air resistance, that is, if the objects fall for a sufficiently short time, and have a sufficiently high mass, and sufficiently small surface area, so that air resistance becomes insignificant.Yes - but only if you can ignore air resistance, that is, if the objects fall for a sufficiently short time, and have a sufficiently high mass, and sufficiently small surface area, so that air resistance becomes insignificant.Yes - but only if you can ignore air resistance, that is, if the objects fall for a sufficiently short time, and have a sufficiently high mass, and sufficiently small surface area, so that air resistance becomes insignificant.Yes - but only if you can ignore air resistance, that is, if the objects fall for a sufficiently short time, and have a sufficiently high mass, and sufficiently small surface area, so that air resistance becomes insignificant.
What happens when two objects of different mass is thrown up. which will reach maximum height if both are thrown with same velocity?
If you ignore air resistance, then they will reach their maximum height at the same time. In order not to ignore air resistance, you would need to know their shapes.
How does wweight affect how things fly through the air?
If you ignore air resistance, weight has no effect at all.
When a guys gazes at you is he mad?
no i dont think so,normally when someone is mad they just ignore you. your straight

A 6.65 kg laundry bag is dropped from rest at an initial height of 3.20 m?
So? Whats the question? _______________________________ It doesn't matter what it is (well, if we ignore air resistance), in Earth's gravity the object will accelerate at 9.8 meters per second per second. Dropped from an altitude H, you can use the formula =(2/9.8*H)^0.5 to calculate the time it takes (in seconds) to the ground. In the absence of air resistance, it will take 0.808 seconds to fall. The speed of the falling object at any moment can be calculated as the time multiplied by 9.8 meters per second per second. In the absence of air resistance, the laundry bag will be falling at a speed of 7.9 meters per second when it hits.
What does a strictly structured change process often ignore?
A strictly structured change process often ignores the ingrained human resistance to change.
What is leakage resistance in RC circuit?
Leakage resistance in any circuit is resistance less than infinity where it is not expected, such as across an insulator. In the ideal sense, all circuits have leakage resistance because no insulator is perfect, but we usually ignore this except in special situations because it does not normally matter in real applications. In an RC circuit, leakage resistance would most typically be across the capacitor.
Can UK assault charges be dropped?
An assault case in the UK is The State vs The Accused, and while charges can be dropped at the request of the victim, it's not automatic. Depending on the circumstances (if the attacker was armed, whether the attack was premeditated) the state might ignore the wishes of the victim.
How does a guy ignore you?
The guy either stops hanging out with you. He won't look at you straight in the eyes. He won't say a word when you pass in front of him.
