A dime. It is smaller and doesn't fight so much air against it.(:

A baseball is hit straight up at an initial velocity of 150MS. what will be the baseballs speed when it hits the ground?
20.40
A 12 kg rocks falls from rest off a cliff and hits the ground in 1.5 s.without considering air resistance what is the rock s velocity just before it hits the ground?
The velocity is gravity acceleration x time or (9.8)(1.5) = 14.7 m/s. The velocity is not dependent on the mass.
An object that falls twice as far will be moving twice as fast when it hits the ground?
No all objects fall at the same speed, unless air resistance is involved
If a stone falls past a bird on a ledge moving at 4 meters per second how fast will the stone be moving just before it hits the ground below 9 seconds later?
92.2m/s
The distance that a free falling object falls is directly proportional to the square of the time it falls (before it hits the ground). If an object fell 91 ft in 2 seconds how far will it have fallen?
The answer is 91 ft, of course!
What hits the ground first quarter or penny?
Depending on the angle that the coins are falling, if they are falling heads down, completely horizontal with the ground, the quarter has more air resistance then the penny, making the penny hit the ground first. If they are on their sides, so the head is completely vertical with the ground, they are both arrow dynamic and the quarter and the penny hit at the same time. as the acceleration of gravity is -9.8 m/s squared, thus making they fall at the same acceleration.
Is a batter awarded first base if the ball hits the ground first in womens fast pitch softball?
If it hits the ground then hits the batter then yes. If it just hits the ground then no.
If a meteror hits the ground it is then called what?
When a meteor hits the ground it is called a meteorite.
Can Lightning and thunder occur simultaneously?
No. Thunder is the result of lightning when it hits the ground. After lightning hits the ground the air expands (because of the increase in temp.) and quickly condenses. That air condensing is what we hear when there is thunder. Because light travels faster than sound we see lightning then hear thunder.
If batted ball hits a base before it hits the ground is it an out?
No, it is simply a ground ball and is in play.
What happens before the tornado hits the ground?
The tornado is a twister before it hits the ground, it just spins in the sky, kind of
Does a hurricane's winds decrease as it reaches higher ground?
A hurricane's winds will start to decrease as soon as it hits land. If it hits high terrain it will weaken faster as the increase in elevation forces more of the moisture to fall as precipitation. This creates in increased risk of flooding.
What happens when a tornado hits the ground?
it stays on the ground until it weakens
Is it a kill when the volleyball drops after hitting it into the net?
Yes you have to play it after it hits the net because if it hits the net and then hits the ground the point goes to the other team
An object in free fall does what till it reaches the ground?
I am not sure because I am only 12, but if it is possible the object may rotate and eventually reach the terminal velocity. It will then start to spin faster and when it hits the ground it may break, disinigrate, or some other form of weathering. I hope this was helpful.
Give examples for non uniform motion?
A falling object, if there is no significant air resistance, will fall faster and faster before it hits the ground. Similarly, a satellite in orbit around the Earth changes its direction, and therefore its velocity, all the time. (In physics, "velocity" describes a speed at a certain direction.)
What do you call a meteor that hits the ground?
It is a meteorite.
